Anyone having trouble with sewing your strips together, take a look at this youtube video.
Susan - you will make 3 separate strip sets from 6 WOF pieces. Cut each strip set into the 3-1/2" wide pieces and then sew into a 90" strip. You will to this 2 more times, and will end up with 3 long pieces about 90" long.
Marytodd - If you don't have enough fabric to cut another strip set and make 3-1/2" cuts, PM me, I think we can make the 2-1/2" wide work. But 3-1/2 would be better.
VickiM - did you offset your strips by 2"? If you got 6 per set, hopefully you will have enough. Can't remember how much I had left when I assembled my quilt.
