I will try that. These are the instructions that I was having trouble following. This is the first time sewing cloth. I usually sew with leather.:
4.) Fold the bag so that the finished (no seams) sides are together. Folding the raw edge under 1/2 inch, overlap the fabric 1 1/2 to 2 inches and sew from C to D (or A to B ). This is the top of the bag. Fold the remaining raw edge under at least 1/4 inch and sew the other edge of the overlap down to fell the seam. This is where you can adjust to insure that your strap will fit into its intended channel.
