I have made several. pick a sweatshirt at least one if not two sizes larger than you normally wear. the color of the shirt will be the inside color of your new jacket, so pick a color you like! cut it apart and mark the left and right sleeves. cut up the middle of the front. i personally leave the ribbing but that is up to you. I cut my strips 2 inches wide and into 8-10-12 inch lenghs and then sew a few together. I only do a few at a time and lay them on the sweatshrit fabric and sew them down straight onto the fabric. I let them overlap at the top and bottom of each peice and trim up later. after you have sewn the fabric strips onto your sweatshirt pieces, then sew the sweatshirt back together. I add a quilt type binding onto the raw edges around the bottom, neckline, sleeves etc. Pockets can be added too with a stanblizer added. mine take me about a long afternoon to cut and sew
