Ooh!! Just seen that one needs over 7mtrs of background fabric and
Don't know if I can afford that :thinking:
I'll be back..........
Is it really background fabric, or does it mean backing fabric?
A big quilt that's say 108" x 108" = 9ft x 9 ft = 3 yards x 3 yards
That would need 2.5 lengths of 42" fabric for the backing
= 2 lengths 3 yards long and one length 1.5 yards long split down the middle and rejoined.
Total 7.5 yards, plus the extra few inches needed for backing so definitley in the region of 7+ metres.
I reckon that if you cut your pieces reasonably small (averaging about 2" x 2") then by the time you have added on the seam allowances and a bit of wastage the total area of fabric is about double the finished area of the quilt - so 7+ metres would be about right for a very big quilt with a design which has roughly half the pieces in "background" fabric and the other half in various colours/patterns.
A King/Queen size quilt doesn't come cheaply!
