What I did was cut all my fabric 2 1/2" by width of fabric. When I had a sack full of stripe [big sack] I started sewing the strips together with a 45 degree angle. When the pile was about 2 1/2 feet high I thought it was going to big enough. I dragged the beginning of the sewn strips across the room [it was a BIG room] & then found the end of the strips and started to sew the long length together. Fold and sew Fold and sew Fold and sew, keep going.
I ended up with a queen/king top. It was fun because some of the strips were short and some extra long.
