have you ever done one of those Mile a Minute quilts where you sew all your strips together end to end to form one really long strip. Then you match the two ends and sew the strip so it is half the length, (in effect you have cut the long strip in half and sewed a quilt top two strips wide. Then the ends are matched again and the quilt is 4 strips wide, then 8, then 16 etc. I bet there is a tute somewhere that says how many strips you need. They are gorgeous fabrics.
