HI thanks os much for these instructions. My fabric says: Pattern single repeat 45.7w x32.5 h.
I'm not sure if this means that the pr is just 32.5? Ie it's not the half drop.
Any advice you can give please? Thanks
If you have the fabric already you should be able to measure the vertical pattern repeat and see from the fabric if it is a half drop or not. If not you need to contact the vendor and ask them. This really is basic information they should be able to tell you.
I’m a great fan of your tutorials, they’ve helped me master Roman blinds and now I hope to make some pinch pleat curtains. I have paid for the videos but can’t access the tips (as soon as I touch them the flash up and disappear before I can read them. A source of some frustration as the first tip seems to be about how to get round being slightly short on fabric. A problem which applies to me as I am using some fabric recycled from a previous pair of curtains that leaves me a out 10cm short on my cut drop. Any ideas how I can access this useful information?
I've had a look and I think what is happening is the TIPs popup when you hover over over them with a mouse. This works fine on a laptop or PC. The hover function doesn't work on touch devices, the popup worked on the phones we tested. On the ipad with safari I can see it doesn't work unless you hold down on it and then clear the "open in new tab " popup.
This is obviously not a good user experience so we will look into presenting the tips another way. Thanks for the feedback.
The Tips you couldn't read are.
IF SHORT OF FABRIC:
If you are short on fabric you could reduce the double hem to double 8cm on full length and double 6cm on sill (you will have to reduce hem on lining accordingly). We do not recommend folding a short turn followed by normal turn as you will have nothing to attach the weights to. You could also add a strip of lining along the top of the curtain wide enough to cover the buckram – you will only need a minimum of 3cm top heading allowance for this – 1cm joining allowance and 2cm to fold over. WE DO NOT RECOMMEND ON SHORTENING BUCKRAM.
PATTERN REPEAT ACCURACY:
If your adjusted cut drop is the same or very close to the cut drop be very careful, as the pattern repeat quoted is not always accurate. Measure your fabric pattern repeat to check!
I have often found pattern repeats to be up to 2 cm out, This is not so much of an issue if you have an excess of fabric on each adjusted cut drop but if you are tight on fabric, this will cause you a lot of problems. For example – Imagine you are working on a fabric with a pattern repeat of 32 cm ( as suggested by the manufacturer ) and you need 5 pattern repeats per adjusted cut drop. When you physically check the fabric, you find that the actual pattern repeat is 30.5 cm, this will leave you short on each cut drop by 7.5cm ( 5 x 1.5 cm from each pattern repeat ) as you always cut at the same position in the pattern not the measured length, so the bottoms of the fabric panels line up. If this has happened to you and you find yourself short on fabric by several cm, you could always use a smaller hem. If you go into the next pattern repeat it could leave you short of fabric. This is why it is always best to mark your cut drops on the fabric BEFORE you cut.
Hi, I'm making single pinch pleat curtains with 300cm wide fabric & lining, so no seams. Am I correct in measuring the track length, times that by my required fullness (1.8) then add the ease + overlap per curtain to get the cut width? And should I add extra for side hem allowance 8cm per curtain (4cm ea side) ? Then work out my pleat size and spacing. Thanks!
That would work.
This is my first attempt at making double pinch pleats. Do I subtract the length of the pole from the width of the curtain to work out the spacing for the pinch pleats
Than you for your assitance
We show you how to calculate pleat sizes and spaces in STEP 9.
Hi - I've just made some edged Roman Blinds using your great tutorial and now starting to make matching patterned Curtains trimmed with a plain fabric 20cm wide leading edge but am having trouble working out how much fabric I need (i.e. how many fabric widths) to account for the additional edging. I haven't decided whether to make double or triple pleats but am working on a fullness of 2.25 and will adjust fullness (and therefore pleats) to be most efficient with fabric
Pole length: 220cm
Finished Curtain width: 118cm
Fullness Ratio: 2.25cm
Fabric width: 137cm (both plain and patterned)
Using your calculator, it suggests I would need 3.6 widths (rounded up to 4) but this doesn't account for the edging.
Is there any easy way to work out what I need or do I have to do it long-hand? If so, am I right to assume that the required fabric width is the finished curtain width X Fullness ratio plus any seam allowances?? (118 x 2.25 = 265.5 plus allowances approx 25)
Using this assumption, I think that I will probably need 1.8 widths of pattern for each curtain PLUS the plain edging. If I am right, should I add the narrow edge to 1 x full width plus 0.8 width OR 2 x 0.9 widths? Which would look best? If 1 + 0.8 is advised, which should be the central panel?
Grateful for your advice - thank you
We would use a minimum fullness ratio of 2.5 for triple pleats, If you
are using 2.25 we would make double pleats working on approx 6 pleats
I'm afraid you have to do the calculations long hand and work it all out. The seam allowances are included within the fullness ratio. The only thing you may need to add to the pole length are returns if you are having them on your curtains.
Rather than specify a trim leading edge width at the start we would actually work out our pleats and spacing first, then calculate the width of the trim so it finishes at the right place on the curtain. ie at the first pleat, halfway through the first pleat, at the end of the first pleat etc.. rather than at a random place on the curtain.
We would join the trim to the patterned fabric (note the trim fabric will have to include fabric for the join seam with the pattern, side turn and the depth of trim). We would then cut the panel down to the width we required taking excess fabric from the other side not the trim side. Of course your extra trim fabric could be making your panel up to the panel width you want so you may not need to cut it down.
Hi I'm making with a fullness of 1.9, I've come up with fabric widths required of 4.456! Do you think I can get away with just 4 widths? I don't want the curtains to be too full or too 'bunched up' when open. Do you think I can get away with 4 widths? Pole length of 326cm!
It would be minimal, We would make up a dummy header and see what it is like before proceeding.
I am making small double pleat curtains for a boat. Measurements are W45cm L 60cm. do I really need a hem allowance of 16cm? Also should I still use 1.9 ratio?
No the 16cm is just what we use for sill length curtains in a house. You can make the hem any size you like.
We would probably go for less than 1.9 for that curtain. Initially thinking of using 5-6cm pleats with 10-9cm gaps. We would make a quick mock up and see if that looks right.
Hi I am making interlined double pinch pleat curtains, I am using 3 widths in each curtain can you tell me where the seams should sit, should they sit inside the pleat or on the flat area between a pleat and also how much spring back should I allow per curtain. Also will the flat area on the inside edges be enough to cover the middle bracket on the pole so not to leave agap in middle when curtains are closed
We tend to have the seam in a gap rather than the pleat to avoid bulk in the pleat.
in STEP 2 when calculating the finished curtain width we add 8cm to each curtain for ease and overlap.
We don't know how big your bracket in the middle is, so you will need to work out what size leading edges you need (to cover this area where there will be no rings) in STEP 9 when working out your pleats.
How much fullness do I need for a hand sewn french pleat valance with a finished width of 145cm plus 15cm x 2 for the returns?
Hi sorry this is going to sound a very basic question. Just trying to work out if we have enough material for double pleat curtains and it states a fullness ratio of 1.9-2.2.... what does this even mean? is it you're stating i need to add an additional 1.9-2.2 for each curtain on top of each curtain measurement. Or an additional 1.9-2.2 on the whole window size, or some other thing that I'm just not getting..sorry just a bit confused(I'm a man lol) as to what i'm adding 1.9-2.2 to. Basically I have been given a pair of very expensive, fantastic triple pleated silk curtains, which are huge and i'm trying to work out if there is enough material in them to make curtain for my 4 windows with the material. Thank you
When you make a curtain you effectively make a flat panel then you pleat
it up , that panel becomes narrower at the heading where the pleats
have pulled it together. If you were making a curtain that was to be 1m
wide when it was pleated with a fullness ratio of 2.2 You would need a
panel 2.2m wide before you pleated it up to make it 1m wide.
My first attempt and double pleats and I forgot to allow for the buck rum depth in my calculation of fabric cut drop. Lengths are cut unfortunately for the first curtain and I don’t have enough excess in the middle panel. Could I hem the top and add the buckram over it and pleat?
You can sew a strip of lining to the top of the fabric to fold over the buckram.
Does the 20 cm hem allowance for full length curtains include the bottom hem and the side hems? Also, do we account for seams of sewing the widths together? Thank you...
No and No
The unusable selvedge edge of the fabric usually accounts for most of the seam allowance when joining.
I am making large curtains ( 3 widths in each curtain)with a appx. 2.5 metre drop. My working bench is reasonable size but not as big as each curtain!!! Can you give any advice on how to handle such large quantities of fabric and still get good results?
It will be hard work, keep it all as flat and smooth as you can when
working on it, Clamps are very good for holding sections in place on the
table, if you haven't got clamps you can use weights. Spring clamps are
pretty cheap on ebay though (make sure you don't buy tiny ones though)
I have a question about the required widths of fabric. Is the amount required for each panel or is it the amount required for the window if making two panels? I am making two panels for my window and based on calculations, I need 2 widths of fabric. I am unsure if that is for each panel or if each panel requires 1 width. Thanks!
The number of widths calculated is what is required to make both
curtains if you are making a pair to cover the window, or a large single
curtain if you are not making a pair.
For simplicity the tuorial and it's examples are based on making a pair of curtains to cover the window.
My fabric has a large floral pattern with a horizontal repeat of 30 cm positioned centrally on the fabric. There will be a lot of waste when joining cut lengths to make sure the pattern actually matches along the seams. Do I calculate number of widths required based on the actual width of the fabric (150 cm) or the width between the centres of the pattern closest to the fabric edges (120 cm)?
Your width measurement for the calculations is the usable width (what it
will be when joined). A standard width is approx 137cm, sometimes a
standard pattern gets printed on wider fabric that leads to wastage when
joining, also have you check if it is a half drop pattern repeat?
I am making a single panel curtain. Using your calculations, 3 widths seems not to be enough, but using 4 widths might be too full. The drapery material is a solid color. Is it ever okay to use a portion of a width of fabric?
Yes of course you can cut down to your required fullness.
If each curtain will be one width of fabric, i.e. I don't have to join any panels, I assume I don't need to calculate adjusted cut drop. Do I just add one pattern repeat do the curtains will match?
We add one pattern repeat to place the position of the pattern on the curtain. Adjusted Cut Drops are then needed for the curtains to match.
