LadyG Posted January 20, 2020 Report Share Posted January 20, 2020 (edited) OK, having a blonde moment. I am buying 56" wide material. Common sense says that the cushion laid flat will take 4 metres of material to cover them overall plus two metres for the side panels. There are four cushions: 2 x 2ft x 4ft 2 x 15" x 4ft all are 5 " thick. SA=2lw+2lh+2hw, so surface area of one large cushion is [2x4]+[2x 0.5]+[2x2]=13 sq ft surface area of small cushion is [2x4]+[2x0.5]+[2x1.25] = 11.5 sq ft TOTAL = 26+23 = 49 sq ft 49 sq ft = 4.55 sq metres. I have not allowed for 3/4" hems. How much material of 56" width? TOP AND BOTTOM OF CUSHIONS length of top cushions add on 0.1ft hems = 1.35+ 2.1 +2.1+ 1.35 = 6.9 ft, length of bottom of cushion as above = 6.9 ft Total length =13.8 ft = 4.2 m of 1 m wide material 4.2/1.44 =3m of 1.44 m wide fabric Edited January 20, 2020 by LadyG Link to comment Share on other sites More sharing options...

OldGoat Posted January 20, 2020 Report Share Posted January 20, 2020 Have you made any allowance for the size of the pattern. Even as a mere male, I acknowledge that it's nice to have all the cushions looking the same / similar... 1 Link to comment Share on other sites More sharing options...
Graham Davis Posted January 20, 2020 Report Share Posted January 20, 2020 And you haven't included a hem allowance. Link to comment Share on other sites More sharing options...
Tony Brooks Posted January 20, 2020 Report Share Posted January 20, 2020 (edited) Have you made an allowance for the salvage edge (I think its called) that you allow on the side of the seams that go inside the cushion. I would think you need to add 10mm/1.2" to each seam for that so the 4ft x 2 ft cushion top becomes 4' 1" x 2' 1", same for the side panels and bottom. If it helps you can get two top/bottom panels side by side in 56" material with enough spare for one side panel (allowing for the salvage) For four cushions that is 16 ft (ignoring the salvage) plus whatever is needed for the side panels you can't get from the spare fabric to the side of the top/bottom pieces. 16 ft linear is about 5 linear meters of 56" wide fabric. Now my head hurts. I would actually use a simple CAD/vector art program to lay it all out on screen to see how it will all fit into 56" fabric. Beaton by Graham re the salvage.

LadyG Posted January 20, 2020 Author Report Share Posted January 20, 2020 Yes the selvedge in this material is likely to bring the actual usable width to 54", though it can be used for hems in this job. It is striped with a fairly small repeat [longitudinal not "railroad"] Link to comment Share on other sites More sharing options...

No, only one panel per cushion width if the stripes are running vertically, which is standard orientation.

Murflynn Posted January 20, 2020 Report Share Posted January 20, 2020 since you seem to have all the facts at your disposal, wouldn't it be possible to sort it out yourself? it is quite elementary, but can only be done by drawing every panel on a piece of paper and fitting the shapes onto a rectangle 56" wide. ................ perhaps in Kansas or South Carolina there is an absence of arithmetical common sense.

New info - striped or patterned materiel. I would still lay it out on a computer because there is likely to be an awfully lot of waste. Actually I would choose a materiel that would be less wasteful 1 Link to comment Share on other sites More sharing options...

Tony, and heavily discounted. I have been unable to contact them today, so have ordered 7m in case someone else buys it. There won't be waste there will be lots of mix 'n match things. Yesterday I found a guy in desperate need of curtains .... I can set up in business! Edited January 20, 2020 by LadyG Link to comment Share on other sites More sharing options...
David Mack Posted January 20, 2020 Report Share Posted January 20, 2020 I see you have edited your original post. I don't think you gave enough information first time around. Working out the total surface area of the cushions will give you a lower bound to the amount of material you will need as it takes no account of the shape and size of the pieces in relation to the fabric width, nor of the pattern orientation or pattern repeat. Best to draw it out as others have said. And if you are going to pipe the edges in the same fabric you will need extra, although much of that can probably come from the offcuts.

I think looms are still imperial, and some fabric has a 1" selvedge, so it is 54" Anyways 7 m will be enough [I think]. If the company would respond to my messages they will be able to confirm.

LadyG Posted January 20, 2020 Author Report Share Posted January 20, 2020 (edited) just got a call from someone from Just Fabrics who I ordered material from, sent two messages and two phone calls on Sunday, and today at 9 00 am and 11 00 am. Regardless they have cut the fabric and will post it today, so apparently that is their idea of customer service, no friendly chat, no advice. Why bother . So they lost my additional sale, and denied me a 15% discount [advertised] PS piping is better done with plain [contrast] or "on the bias". I am not sure if the "risk" of piping is worth it, I will have to experiment. Edited January 20, 2020 by LadyG Link to comment Share on other sites More sharing options...
