I like to make short Y’s off those long cuts prior to mounting. I’ve never been good at sewing a long Y on the form. Ages ago George recommended laying them on a table, folding the hair side in, matching the sides and placing reference marks on each side to keep the sides even. Since I don’t have table space for those big capes, I began hanging them by the nose, placing a temporary suture at the bottom of the Y, and the begin sewing about 10 inches down. The hanging cape allows easy check to make sure one side isn’t getting ahead of the other. I can sew quicker this way. Every 4 inches, I place a “lock stitch” to hold everything to that point tightly sutured. I use a roll stitch, going from hair side to skin side. This 32” stitch took me approximately 15 minutes.
