I'm glad you liked that one too. I threw it in at the last minute - it's the same as 3 except I removed the wreaths from all the setting triangles. I like the floating effect, plus it gives you a lot of space to do amazing quilting.
I think you need more than 5 yards of background fabric.
Granted, you're not doing a lot of piecing with it but still ---EQ is no help with this - who knows how it's figuring out yardage on this setting. It wants 9 yards.
I would be comfortable with 7 yards.
First off, you're cutting 12"plus blocks, which means you'll only be getting 3 across WOF. And you need 32 of them.
If you cut the borders lengthwise, that's 3 yards, and you'll be able to get 7-9 blocks out of the remaining yardage.
To get the other 25 blocks, at 3 across WOF, that will take another ~2.5 yards.
Plus you need the setting triangles, so figure another yard for those.
So that's 6.5 yards for a back of the envelope guesstimate. Hmmm, maybe the EQ yardage isn't so far off the wall.
I wouldn't have less then 7 yards on hand.
Here's a bigger picture of the wreath - I put 16 petals (xmas lights) on each one. I think it fills it nicely......plus you'll have the little stem which I couldn't be bothered with. Looked like it was the same on the original (?)
