Lined Roman Blind
WORKROOM METHOD
Step 4: Calculate Lining Quantity
Printable Worksheet
Printable Worksheet

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

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



If you are using rod pocket tape RPA=0, please see ROD POCKET TAPE notes below.

LINING QUANTITY REQUIRED

The minimum amount of lining required to make a single width roman blind is

LINING CUT DROP + TRIMMING ALLOWANCE.

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

  EXTRA INSTRUCTIONS


If you are using Rod Pocket Tape you will need to disregard the rod pocket allowance as you will not be making the rod pockets out of the lining. Therefore the ROD POCKET ALLOWANCE (RPA) = 0 when calculating the LINING CUT DROP.



Questions & Comments

Hi there.

I’ve finished making some Roman blinds using rod pocket tape. It seems to me that the rods are a bit redundant in the way they hang in the tape, there seems to be so much space in the tape that they don’t seem to be what lifts the fold, as much as the stab stitches. Is this the same when using rings and rod pockets made from the lining? I can’t quite work out what the function of the rods is in that case! Would love to understand exactly what they are there for. Many thanks, Julie

The rods and bottom bar hold the shape of the roman blind when it is pulled up. If you don't have them that is called a relaxed roman blind and when you pull it up it would look like this.

Thank you again for all wonderful help here.

Is the type of Roman Blind lining used personal preference? I’ve heard lots of people say they prefer to use black out only, or only bonded black out lining, even when it’s not in a bedroom. This is so you don’t get the shadow of the side turnings showing through and for a better look to the blind. Is this something you recommend?

SewHelpful:  

We tend to mainly make blackout or bonded blackout roman blinds in the workroom. for the following reasons

 1.    The blackout inside gives the blind a bit more body and helps it keep it's shape. 

 2.    The blackout can help protect the fabric from sun damage.

Whether we use standard blackout or bonded depends on the thickness of the fabric and whether the customer is looking for a softer thicker blind.

Hi,

I'm looking at fibreglass rods from Merrick & Day that are 4mm diameter. What is the diameter of the rods you refer to? Can I assume these are the same?

Thanks

SewHelpful:  

Yes

Ginny

I want a standard, non-blackout, lining but not too flimsy. What weight lining do you recommend? Thank you

SewHelpful:  

The standard lining we use in the workroom nowadays is 200gsm.

Annette

Hi, Do you have any advice regarding the type of lining material I should use for 100% wool fabric? I have read that poly cotton or twill is better than pure cotton. I am making both roman blinds and curtains. Thanks

SewHelpful:  

We wouldn't use any special lining, we would just use our standard choice.

Lisa

If using rod tape do you need to add any allowance

SewHelpful:  

You do not need the allowance for rod pockets because you would be sewing the tape onto flat lining and not forming any rod pockets with the lining. You will of course still need the heading and hem allowances.

Jayne

Is it always 5cm for the heading allowance in the lining cut drop or does it depend on the headrail allowance of 1.5 x the depth of the headrail ? My headrail depth is 4cm x 1.5 = 6, so would I allow 6cm for this or doesn't it matter ? Thank you

SewHelpful:  

The 5cm heading allowance for the lining is an extra 5cm of lining used when making up the blind's lining and forming the heading. The headrail allowance is used when calculating the blind's dimensions. It ensures the blind folds do not hit the headrail when pulled up. They have nothing to do with each other at all.

I am about to start a blind 60 inches wide, so I will use a central panel of one width of fabric, with a strip each side to make the width. Should I do the same with the lining, so the seams line up, or should I just have a central seam in the lining?

SewHelpful:  

If the drop of the blind is no more than about 119cm you can usually railroad the lining (using it sideways to avoid any joins). Otherwise we would make the lining panels up the same as the fabric so the seams line up.

It can be a real pain trying to get the rods through at the joins in the lining as they sometimes catch on the flap of lining inside the pocket and get stuck (occasionally you have to unpick it slightly to get the rod through then sew back up). Using rod pocket tape would avoid that frustration.

Samantha

About the lining: my understanding is that if I am using rod tape, lining cut should be like finished blind (finished length and width).

SewHelpful:  

No not correct for length:

If you see in the instructions on this page and the next STEP 

Using rod tape

Lining cut length = blind length + 5cm Heading allowance + 9cm Hem allowance


Yes correct for width:

In the STEP 5 (next step) the lining is cut to the finished width of the blind 

Sharon

If adding a lining panel, do you need to distribute evenly to each side like with the main material or do you just add it on as one piece?

Thanks.

SewHelpful:  

We would balance the lining as we do with the fabric with a strip on either side. The lining seams probably won't align with the fabric seams but this is not a bad thing as there could be too much bulk if they are on top of each other.

Simone

Hello, Thank you so much for your videos & written information. I am absolutely loving them.

Question -I am trying to decide if I should use rod pocket tape or using the lining to make the pockets. What are the pros & cons of each?

SewHelpful:  

For a more professional finish make the pockets out of the lining. We dont use tape in the workshop.

Elizabeth

Roman blind width 212cm and drop 112cm. Is it ok to place lining across the way as its width is more than the finished drop of my fabric - would save joining and also save on amount of lining needed - just not sure if you can place two materials together with different grains...

SewHelpful:  

If the width of the lining is less than the required lining  cut drop, using it sideways (railroading) would avoid joins. We have done this many times with the linings we use.

Jackie

Hello. And thank you for the tutorial. I am planning a blind for patio windows so it will be wider than the 137 standard width. Do you recommend cutting the lining so that it goes either side of a middle piece, as with the facing fabric, or is it ok to have a central seam? Thanks

SewHelpful:  

We would make with a piece either side. You can buy double width lining to avoid the joins.
