Can I make sure I have got this right? The total length of the cut fabric should be [the height of the area to be filled] + [an allowance for the space taken up by the pulled-up pleats and batten ie "headrail"] + [an allowance for finishing at the top ie "heading"] + bottom hem allowance.
No that sounds wrong.
The headrail allowance is nothing to do with the cut length of fabric or lining. It is used to determine the rod pocket positions and consequently where the folds form when the blind is pulled up.
The cut length of the fabric is as stated in the previous STEP, STEP 3.
Am I right in thinking that the cut drop lining measurement is different for interlined blinds i.e drop + 7cm for interlined but drop + (5+9cm)for lined (not inc. rod pocket allowance?
Yes the hems of the linings are different. The interlined blind only has
a 2cm hem allowance and the lined blind has a 9cm hem allowance. If you
read through both tutorials you will see how the hems are constructed
Thinking of a 3m. wide roman blind should the joins on the interlining fabric correspond with the fabric seam lines?
We don't necessarily line the seams up. A 3m blind is quite an
undertaking you will have to be very accurate getting it straight and
square as any errors are amplified. Also an interlined 3m blind will be
heavy you will need a geared mechanism to lift it, we would not make one
with a wooden batten.
Hi, I just want to say that your tutorials are great, I have bought the videos for blind making, there is just a couple of questions.
1) if the rod channels are 2.5cms once folded, why does it say I add 2.5cms x number of rods, if the rod channels are 2.5cms when folded, would I not add 5cms per rod used ? Sorry if that is a stupid question.
2) I can't find anywhere on the videos that shows how you attach the rod pockets across the width of the blind. Thanks for any help
1. We are not sure where you are getting the 2.5cm once folded from. The pockets will be 1.25cm deep once folded in our case.
2. Not sure if you are talking about rod pocket tape here or stab stitching. The tutorial is for a blind made with traditional rod pockets made from the lining not with rod pocket tape. hence no video for that. (there is some info about using tape in the lined blind tutorial). If you are asking about how we attach the lining across the width of the rod pocket to the blind that is done in the second part of STEP 8 with STAB STITCHES.
Apologies, am getting confused working out the drop for the interlining for an interlined blind. My drop is 96cm, so for the fabric this works out at 110 (96 + 5 + 9), lining 103 (96 + 5 + 2), interlining the tutorial says same as for plain fabric so can I confirm with you that this is 110 again (96 + 5 + 9) this seems too much. I would have thought a more similar length to the lining than the fabric?
You haven't included any lining for integral rod pockets (are you using
tape?). This may well make the lining cut drop longer than the plain
fabric cut drop.
The instructions are correct we estimate the amount of intelining required as the same as the cut drop for plain fabric. There is trimming down in the make up process.
I am considering interlining my blinds however I didnt know whether to use the Bonded twill lining & Interlining. Have you used this or would it be too stiff for each fold?
We have written a blog article about interlinings in our blog
We almost always use sarille in roman blinds.
Please can you recommend a weight of Sarille for interlining. I bought bump but it looks far too think.
We made a short guide on interlinings in our Blog . INTERLINING GUIDE
The weight we use depends on the weight of the fabric and what look and feel we are going for so it varies. We don't tend to use really heavy interlinings in blinds though. A light Sarille is usually a good choice in blinds.
I am thinking of using black out lining to make blinds for my daughters room. Some samples i have got are very stiff. Do you have any recommendations regarding black out lining, weight etc? Thanks
They are generally a bit rubbery, our blackout lining comes from a
wholesaler which we buy per roll, it's called a supreme soft blackout,
I'm afraid there is no weight information.
