You sew all the strips into one long strip and then take both free ends and sew until you get to the fold. You cut the fold with scissors, now you have a two long strips sewed together. Fold the strips right sides together and sew from the free ends until you get to the fold. Cut the fold. Now fold that strip set right sides together and sew till you get to the fold. Keep going until you are done. I hope you can understand what I am saying. I have only done one, but they are pretty easy once you get it. Post a picture to show us what you have so far. Gina
