I've been doing math. :-) This has been very accurate. I cut 7" blocks. The lady at the lqs said I'd get six blocks per strip, but I can only get five--and one 4" which I do use. So if I like the 9 by 11 block size--that's 99 blocks for the front and 99 for the back. If I want four fabrics, that's 25 blocks per fabric. So...since I get five blocks from one strip, I need five strips. 5 x 7 is 35"--that is easy enough but divided by 36" to determine yardage--it'd be .97 of a yard of each of four fabrics. Just for the record--I'd go 1.25 yards to play it safe. ;-) For the back of this next one I'm using all the same fabric. So getting five blocks per strip, and 99 blocks needs 19.8 strips--obviously round to 20 strips. Twenty 7" strips = 140" and divide that by 36" to determine yardage and it comes to 3.88 yards--which of course I'd round to 4.25--just to be safe. lol Can you tell I've learned my lesson by buying a bit more than I think I need?
So--bottom line--to make the size I'm making--54" by 66" you need four yards of fabric for front and four more for the back--total of eight yards.
If one is using a different size block--or wants five fabrics for the front--the calculations are easy.
Hope that helps!
Anyway--here are my fabrics for the next one. Strips are all cut--just need to get them into blocks. I also need to start from scratch with batting squares--I used all I had in the last one. I don't like cutting batting. But--to give a hug-to-go--I'm willing!
Colors--I read somewhere long ago that for a calming effect--the hues must all be similar--even if one is a bit darker than another--contrast much be low. So--that's what I was going for here. The recipient's favorite color is yellow--so that one will be the back. It is BRIGHT!
Two of the fabrics are Buggy Barn flannels--LOVE them. The green is Stonehedge.
