After each seam, you cut the fold then put the ends together and sew the next seam. So start with the long bias type, fold with right sides together, cut fold, fold with right sides and edges together, cut fold, etc. Make sure the strips are not twisted before you start the seam. Mine weren't but 54" wide i believe but 50" long. Give or take a little for seams. I can't remeber the exact measurements.
