The latest staple of my wardrobe I've designed/made by recycling. They're all made with old tracksuits, ribbing and a few odd bits of jersey. If you can get a large pair of tracksuit bottoms, particularly one without outer side seams, when opened up each leg is large enough to make the front or back panel. It's based on a modification of my basic T-shirt pattern, sleeves lengthened, added front pocket in some cases. Hoods are not hard to do, two matching pieces of the right shape stitched around the collar in much the same way as a normal collar band would be. Ribbing for cuffs and hem can be obtained from a variety of source garments, or if you don't have any, sufficiently stretchy jersey will do. All hand-prints by me.
