I have 2-1/2" strips that I'm wanting to use for a 12" finished square for a swap. I've made squares that were just whatever size they ended up, but not ones that were a specific size before. It's looking like I won't be able to do a square that utilizes the diagonal as the edge of the square and have it come out the correct size.

Would I be able to use a different width strips and make it work? If so what width would they need to be?

Do you have a specific block in mind? I'm trying to visualize. :-D

Sorry...if I don't have a picture already in my computer I don't know how to get it posted....will try to describe the one I have in mind.

3 or 4 (could be more) strips stitched together, cut into squares, then cut diagonally, arranged back into squares with the diagonal as the outer edge of the square and the long strips forming a pinwheel/windmill in the center of the block.

Will see if I can figure out this webcam and maybe I can get a picture!

OK. I think I know the pattern that you are talking about. Let me check I think I've seen it in one of my quilting mags.

Right back!!

I found the pattern you need to make the quilt , its in The Quilter magazine issue March 2007, the strips are just a tad thinner than you used but it can be done.

you can use it to make a 12 by 12 square. The strips are 2 inches wide so you might have to adjust the patter just a little

I'll be dipped, I can't find it here. Maybe I saw it on a site.

Are you all set? I can't find the pattern, but after thinking about it I probably would add a 1/2" all around. So 12 1/2" becomes 13" to compensate for your other two 1/4" seams. Does this math work for you?

Was it the Twist & Turn Disappearing 9 Patch? Here's one: http://www.quiltingboard.com/t-16190-1.htm It is a variation on the regular D9P and creates a pinwheel in the center if you turn the pieces correctly.

Here is another that is a string or strip quilt--sort of a twisted Rail Fence: http://quiltville.com/striptwist.shtml

And another that sews squares onto strips and then cuts on the diagonal of the square: http://www.quiltingboard.com/t-49685-1.htm
