    FINISHED CURTAIN WIDTH

    For a pair of curtains the Finished Curtain Width for each curtain is half the pole length plus a figure for ease and overlap*.

    We use the following for ease and overlap per curtain on a pair of curtains.

    Pole Length Ease + Overlap per curtain
    120cm7cm
    160cm8cm
    180cm8.5cm
    200cm9cm
    220cm9.5cm
    240cm10cm
    260cm10.5cm
    280cm11cm
    300cm11.5cm
    320cm12cm

    *Note if you are returning your curtain to the wall (continuing the outside flap of the curtain from the pole to the wall) you will also need to add the distance of the curtain pole to the wall to the finished curtain width.

    FINISHED CURTAIN LENGTH

    To calculate the Finished Curtain Length add the Hook to Top and Hook Drop measurements together: The calculation for the finished curtain length is then.

    CHOOSE YOUR PLEAT DEPTH

    The Pleat Depth
    of the double pleats you wish to make will determine the size of the buckram needed and have a small affect on the amount of fabric and lining you require (as calculated in step 3 and step 4). The depth of your pleat is the depth of your buckram.

    This is a design decision limited only by the sizes of buckram you have available to you. Note you can cut buckram down if needed.

    For guidance generally we would make sill length curtains with a 10cm (4") buckram and floor length curtains with a 12.5cm (5") or sometimes 15cm (6") buckram.

    PLEAT SIZES & SPACING

    THE NORMAL PROCESS

    When making a pair of hand pleated curtains we NORMALLY calculate the pleat and gap sizes in STEP 9. This is the process we follow.

    • Decide now how full you want your curtains to be. (see below)
    • Calculate to the nearest half width how many widths/half widths of fabric each curtain needs to be made with in STEP 3.
    • Make up the flat curtain panel (with the approriate number of widths/half widths wide) ready to be pleated in STEP 9.
    • At STEP 9 measure the exact width of the made up curtain panel and THEN calculate the pleat sizes and spacing.

    HOW TO CHOOSE THE FULLNESS OF YOUR CURTAINS

    When deciding how full we want our curtains to be we talk in terms of Fullness Ratio. Fullness Ratio is the ratio of the width of the curtain before pleating to its finished width when pleated or gathered. The higher the fullness ratio the more gathered and heavier the curtains will be.

    We recommend a Fullness Ratio of 1.9 to 2.2 for a double pleated curtain. In our opinion 2.5 may be too much for a double pleat. The curtains will work with a fullness ratio of 1.9 which will save you fabric, however this will not give you an overly full look but can be really effective if you are looking for a light, delicate window treatment. Consequently double pleat is a great one to go for if you do not want to go into the next width of fabric and it can also look really good with very small pleats such as 6 – 8cm.

    The curtains made in the videos of this tutorial have a 1.9 fullness ratio.

    Thank you so much for putting in all the effort to get instructions and videos done for all your tutorials they are great. I'm sure I'm not the only one that has been especially looking forward to this tutorial! :)

    Anyway, my question is about buckram. In general, I've found that there are different types of stiffness for buckrams - do you use a light, firm or extra firm buckram on the curtains?
    Sew Helpful
    For lined curtains we use single sided fusible cotton buckram (That is what we use in the videos it only comes in one weight from our supplier). For a lighter interlined curtain we would use a medium weight sew in cotton buckram (not fusible) and for heavier interlined curtains we would use heavy weight sew in cotton buckram (not fusible).
    Jane
    Great tutorial thanks. Each time you press the seam open (lining or main fabrics) are you using steam ?Also, can you use sew in buckram if you didn't want to use fusible ? I know you haven't interlined but, if you did, where would you end this at the top of the curtain please ? Thank you in advance.
    Sew Helpful
    We do not use steam to press open the seams (see videos).

    We use fusible buckram in a lined curtain as it holds the buckram in place and it gives it a nice tight fold. If you want to try and sew buckram in instead  that is your choice but not what we would do.

    We make the interlined heading up differently, that tutorial will come later.
    Nicola
    When might the interlined tutorial be coming, please?
    Sew Helpful
    We are presently making 6 Roman blind tutorials. The interlined curtain tutorials will be after that. I don't expect them to be ready for 3 months.

    My curtain return to the wall has to be 10cm and the curtain will then make a right-angle turn to follow the curtain pole. Should I put the first triple pleat to coincide with this turn or have the first pleat within the return. I imagine it should be at the corner but I'm asking in case you feel it would result in the curtain splaying out too much. Thanks
    Sew Helpful
    As you will see in the image above we do not put a pleat on the return to the wall.
    Louise
    Hello - thank you for the tutorial, it is very helpful. Is there a rule to calculate how wide a double pleat curtain would be when pushed back? I'd like to use that to work out how wide my curtain pole should be. Thank you
    Sew Helpful
    A double width, lined double pleat curtain will have a  stack back of appox 25 to 30cm. There will be variation due to fabric weight etc.
    Claire
    Hi - I want to make a triple pleat curtain, but I need it to hang 4cm above the pole as the glass on my window goes to the ceiling and heading tape would be seen. It is a dress curtain so wouldn't be opened and closed. Would a triple pleat curtain work.
    Sew Helpful
    Yes it would work, you will need to get the gap sizes the right proportion as they will stick out forwards between the pleats as they will hit the pole behind.
    Danielle
    How much fabric would I need for double pleat curtains? Plain fabric and using 5" buckram
    Pole width= 63"
    Pole to floor length= 83"
    I'm sorry I'm stuggling to work it out, thank you

    I'm sorry we do not make calculations for people.

    When you add on a return to the curtain for it to meet the wall how does it stay in place and not flap out to the side. Or how does it stay at a 90 degree angle?
    Sew Helpful
    With a return back to the wall, to hold it 90 degrees to the wall we usually

    1. Hold it in place with a small wooden block attached to the wall with a hook velcro edge and sew soft loop velcro to the back of the heading near the edge. Then press the 2 together.
    2. Fix a screw eye to the wall an put a pin hook near the end of the return and hook the return to the wall.
    Sorry I dont have any images available at the moment.

    I am making curtains for two windows in the same room. One is sill length and one is floor length. What pleat depth would you recommend? Would you use the same depth for both? Thank you
    Sew Helpful
    We would use the same size for both, 5 inch buckram in this case.

    Also for a single pair we position a pattern at the bottom of the curtain, but with 2 pairs of different length curtains in a room we would match the vertical pattern position on the headings (Top) of each pair.

    How may Pleats recommended per Metre?
    Sew Helpful
    We work in widths of fabric, and usually its about 6 pleats per width for a double pleated curtain.
    Amy
    How many pleats are recommended per metre for triple pleated curtains?
    Sew Helpful
    Generally we look to use 5 to 6 double pleats per width depending on what size pleat we want. For triple pleats we usually use 4 per width as a starting point when deciding.
    Bronwen
    What thread do you use when hand sewing and when machine sewing the pleats. I have found the video very useful but didn't see this information.

    Secondly if doing a return to the wall do you miss out the last hook on the return which you place one cm from the end?
    Sew Helpful
    We use varous threads, Gutermann, Coats Duet, 100% cotton, 100% Polyester. For us the important factor is the colour match.

    With regards to returns, quite often we fix a wooden block to the wall and attach the return to the wall to hold it in place at the right position, either with velcro (loop sewn on inside of curtain, hook on block) or hook through an eyelet.

    I have a centre bracket in my pole. Should I increase the overlap provision?
    Sew Helpful
    No, you should ok unless it is a really chunky bracket and you might want an extra cm on the leading edge in that case.
    Sharron
    I am about to calculate my double pinch pleats. I allowed for a return to the wall, which is 5cm. I am using track with finials. Am I right in presuming that the end pleat is hung on the last fixed hook at the end of the track, just before the finial, and the return free from there on? Does it need any special treatment to fold back to the wall.?
    Sew Helpful
    You need something to hold it on the wall. We would usually cover a piece of wooden batten with lining, attach that vertically to the wall, attach velcro hook down the side of the batten that the curtain will touch onto, Then sew loop velcro on the inside of the curtain so we can hold the curtain in place to the wall.

    Hi I’m wanting to use quite a heavy chenille fabric for my curtains. Is this suitable for pinch pleating.
    Sew Helpful
    Yes

    You won't be able to make small dainty pleats with thicker fabric and especially with interlined curtains and thick fabrics you need to make sure your machine and needle is strong enough to stitch through when sewing the pleats into the heading
