Welcome Eggy. Sorry no one has answered you yet. The board has slowed down considerably over the years. Short version: mark your seams AND reference MARKS on the foam with a sharpie--cut an over sized piece or pattern material for each panel,pin it on and add 3/8 seam allowance and reference marks. [usually faster and more accurate than using old skins as patterns]. Gluing and or sewing 1/4 or 1/2 foam to the backs of the top panels HIDES A LOT OF UGLY. Make your own welt!. Till you get more experience pattern making--don't diddle with pules. Cut your borders oversized enough to wrap around a piece of wire or plastic welt cord as you hog ring it on. Trim excess.Welcome and good luck.
