This website is viewed globally and at the last time of looking had been used by people from 136 different countries.

The instructions and videos on this website show you the traditional methods of making a roman blind. Many countries have introduced safety regulations with respect to child safety, to reduce the threat of injury or strangulation to young children from the cords of roman blinds.

It is your responsibilty to find out what the regulations are for your country and modify these instructions to make your blind compliant with those regulations

Examples of safety advice and rules used by some countries of the world are:

  • Do not place furniture or beds near windows where children can climb up and access the blind cords.
  • For roman blinds with rod pockets greater than 20cms apart at any point a breakaway device must be used on each cord.
  • The cleat must be 150cms from the floor and accumulate all/most of the cord – only a single cord of no more than 20cms can hang below the cleat.
  • The bottom loop of the chain or cord must be 150cms from the floor and secured with a safety device OR If the operating chain/cord has a breakaway device then the bottom loop of the cord/chain can be 60cms from the floor.
  • Some countries require that all the blind's components have been tested and certified when used together.

    Printable Worksheet
    Printable Worksheet

    This tutorial is based on using one width of fabric to make a blind. Fabric is usually approx 137cm wide, so most blinds less than 127cm wide will only need one width of fabric (check your fabric width).

    The fabric panel is cut to the following size to make the blind:



    FABRIC QUANTITY REQUIRED (Plain Fabric)

    The PLAIN FABRIC required to make a single width roman blind is

    FABRIC CUT DROP + TRIMMING ALLOWANCE

    PRO TIP: Add at least an extra 6cm trimming allowance to the cut drop to ensure that the fabric can be cut square during the making process.

    PATTERNED FABRIC differs from PLAIN FABRIC as extra fabric is needed to take into account the placement of the pattern on the blind.

    Making a blind in PATTERNED FABRIC with NO JOINED WIDTHS will require the FABRIC CUT DROP plus ONE PATTERN REPEAT to place the pattern on the blind.

      EXTRA INSTRUCTIONS

    If you are covering a batten in fabric there may be enough excess fabric from offcuts if the blind is narrow. Otherwise you will need 30cm of fabric per width used for each batten.

    Note battens for blinds outside the recess are generally covered in fabric (as they can be seen), battens for blinds inside the recess are hidden so are usually covered in lining.

    FAQs

    There are 2 types of pattern repeat on a patterned fabric, Horizontal and Vertical. We are generally more interested in the vertical pattern repeat when making curtains and blinds and if only one pattern repeat is given by a manufacturer we would expect it to be the vertical one.

    VERTICAL PATTERN REPEAT

    The distance up or down the fabric, the pattern repeats itself.


    HORIZONTAL PATTERN REPEAT

    The distance across the fabric, the pattern repeats itself.

    Hi,

    I find your site is the most useful thing I stumbled upon this year so thank you. I just have a question about pattern matching on multiple blinds. If I am making 3 blinds for one window and like the outer two blinds to have their patterns lined up but the middle one starting at an alternate pattern point, how do I make adjustments for that when calculating fabric qty?

    SewHelpful:

    First just a quick tip, when we make blinds side by side in a window we always have the patterns lined up as we think it looks right to the eye.

    However with regard to the question.

    The calculation is based on making a single blind and includes an extra pattern repeat to position the fabric where you want on the blind. So if you have included an extra pattern repeat for each blind you could start each blind in whatever position you wanted on the pattern.

    However if you are making 3 blinds of the SAME LENGTH and are starting them ALL AT THE SAME POSITION in the fabric you will not need to buy that much fabric. You would only need to add 1 extra pattern repeat to position the pattern on the first blind, then cut the adjusted cut drops for the 3 blinds.

    In your case though with 2 blinds the same and one different, provided they are ALL THE SAME LENGTH, you would need to add 2 extra pattern repeats to the fabric quantity calculation. Use the first pattern repeat to set the position for your outer blinds and cut the adjusted cut drops for those blinds. Then with the remaining fabric you will have another extra pattern repeat to position the pattern for that one and cut its adjusted cut drop(s).

    I am using a striped fabric so there is no vertical pattern repeat, it is horizontal. Do I treat the drop as having no pattern and just pay attention to the pattern repeat when calculating the 3 panel width?

    SewHelpful:

    Yes as there is no vertical pattern repeat treat the drop as having zero pattern repeat. Join the widths matching the pattern then pay attention that the stripes on each side of the blind are balanced.

    I'm getting a bit confused with the calculating of the fabric cut drop. Where you mention the "heading allowance" is this the same thing as "headrail allowance" mentioned in step 2?

    The reason I ask is that my headrail allowance is 5.4cm (I am using 36mm batten). So would it be: Finished Blind Drop + 5.4cm + 9cm?

    SewHelpful:

    Heading Allowance and Headrail Allowance are completely different.

    The Headrail allowance is a measurement used when calculating the position of the folds and the dimensions of the blind.

    The Heading allowance is the excess lining or fabric you need at the top of the lining or fabric panel when making the heading of the blind.

    It should be: Fabric Cut Drop = Finished Blind Drop + 5cm + 9cm

    I need 4 blinds and there is sufficient width of fabric for 2 blinds. how do I calculate the pattern drop for this

    SewHelpful:

    I'm afraid we dont make calculations for people.

    If you are trying to get 2 blinds out of a width I guess they are quite narrow and your pattern repeat  is quite small or the fabric is wide. We position the pattern vertically and horizontally on the pattern when making a set of blinds so they all look the same. Consequently we do not often manage to get 2 side by side out of a standard width.

    I am making Roman blinds for a room with two different sizes of window. One blind is 80 cm long and the other is 112, and the windows also sit at different heights. The fabric is a check and the blinds are scalloped at the bottom. Should I try and pattern match and, if so, do I make the blinds match at the top edge or the bottom?

    SewHelpful:

    We would pattern match to the top of the blind, so the blinds look the same when pulled up.

    Dependant on the layout of the room and windows, If any of the blinds are outside the recess we would look to see if it  might look better raising the position of one above the recess so they are both the same height above the floor.

    Hi - I am making dress curtains (to go with a roman blind) and a bit stuck. Please could you advise if there is a general rule of thumb to calculate how much fabric I need to buy for the dress curtains. As they don't need to draw together do I just calculate a full pair and quarter it? halve it? Etc. I don't want to buy too much fabric unnecessarily but also don't want them to look on the 'skinny' side. Many thanks

    SewHelpful:

    Whilst dress curtains are not meant to be drawn they should look functional as well as decorative and the mistake is often made of making them too skimpy to avoid using too much fabric. Really it depends on the length of your pole/ pleating method and desired look that really only you can judge. I would say though that anything less than 1.5 widths per curtain could look too minimal (though if your pole is only 140cm 1 width would be fine). Also interlining and hand pleating will give a fuller effect and may require less widths but I would still suggest 1.5 minimum per curtain.

    I am making two Roman blind, next to each other and different lengths. I don't need to match the pattern. How can I ensure the fold widths are the same? One is 124cm and the other 144cm. Thanks

    SewHelpful:

    We dont make calculations for people.

    To make the 2 blinds have the same fold size so they both fold at the same point as they go up and down you would need one complete section added to the bottom of the longer blind so your pleat sections would be 10cm, (20cm fold).

    However the size of your folds going up and down is not really as important as the size of the blind in the up position,  as usually you have the blind either up or down. You will probably want the 2 blinds to be the same size in the up position. By varying your headrail allowance you could keep the top sections of the blinds the same depth but with different fold sizes (pleat section depths) and the same number of pleat sections.

    I have used your instructions above to calculate fabric qty needed for 3 blinds to fit in bay window and a side window. They will all be made out of the same fabric with a pattern repeat of 80cm. Am I correct by using the adjusted drop calculation for each plus 1 pattern repeat in total even though I have 3 single width blinds and 1 joined width blind to match. The drop is 216cm for each

    SewHelpful:

    For a standard pattern repeat.

    For 4 individual blinds, the same drop, that you want to start at the same point in the pattern. Yes you would only need one pattern repeat to position the fabric pattern and all the adjusted cut drops would be the same.

    In a bay if you intend to try and continue the pattern horizontally from blind to blind you will need to make the centre blind first, then match the side blinds to it either side. The width of your side blinds and the horizontal pattern repeat of the fabric will determine if this is possible.

    Wendy

    Your previous comments have been really helpful- thank you.

    I want to make blinds with a contrasting border of 6cm. How would you attached these borders - are they attached and then treated as part of the face fabric.

    I also need to add tab top heading - how do I attach these?

    SewHelpful:

    We would make up the fabric panel with the borders , then treat it as one panel trimming and squaring off. You will obviously have to take into account the fabric needed for the side turns when calculating the width of the fabric strips to join to each side.

    We would join the panels with a plain seam.

    Unfortunately we don't have the resources to write instructions on how to make a tab top heading, which is a bit beyond the scope of the tutorial.

    I am making 3 blinds in the same fabric, all of which are slightly over one width of fabric and will therefore require joining/pattern matching. I'm comfortable calculating the fabric quantities/pattern repeat for one blind - but is there a way to do this for more than one blind to ensure best use of fabric quantities? Thanks

    SewHelpful:

    We balance the blind with the fabric added to either side. If the patterned fabric is expensive, you could use a cheaper complimentary plain fabric as edge strips either side. 

    However just using the patterned fabric.

    If the blinds are all the same length you will not need an extra pattern repeat for each blind to make sure they start at the same point in the pattern. You just need one extra pattern repeat to position the pattern on the first blind. If the the horizontal pattern repeat is small enough you may be able to get more than 2 side strips out of one drop (that will take some working out).

    I am making two roman blinds for two windows which sit approx 1 metre apart. The window widths are different although the drop is the same. I’m. To sure yet whether to recess the blinds or not - open to recommendations!

    How do I arrange the pattern - do I match both blinds from the same centre point on each window .... or do I arrange it so that the pattern runs from left to right across both windows?

    Thank you for your advice!

    SewHelpful:

    We would go for same centre point of pattern on each blind.

    Joy

    Is a Roman blind 226.5 wide too wide for a Roman blind? Being that the folds are stitched on the lining only, will the folds droop in the middle? Would appreciate a reply soon as I’m ready to start. Thanking you in anticipation.

    SewHelpful:

    You can make blinds that wide and they wont sag in the middle if they are made properly. It is quite an ambitious size for a first blind though.

    Jenny

    Can you tell me if you can turn the fabric instead of joining widths of plain fabric for roman blinds.

    Somebody told me you can but I always thought there would be a weave issue.

    SewHelpful:

    We have done it many times on blinds and never had a probem with the weave on the fabrics we have used. Obviously we can't say how your fabric will hang. 

    Remember you can only use the the fabric sideways (railroaded) up to a certain length blind as you are restricted by the width of the fabric.

    Jules

    I am making a Roman blind finished width 135cms. The fabric is 138 cms wide. Would you add a small strip of fabric on one side or join a width either side of blind.

    SewHelpful:

    We never join on one side. In the workshop we would add a strip of fabric to each side. We would  also give the customer the option of not using the full width of the fabric and having a complimentary plain 10cm fabric border down each side.
