I made a single layer 8 oz belt from scraps about 50 years ago. Cut the scrap into 1.25" x 3.25" pieces and laced them together, then laced the perimeter of the whole belt. Wore it for many years, until it got too short. I used a bag of scrap lace, most of it not beveled, and inconsistent width. Did double loop lacing style. Looks kind of ratty now after sitting in a drawer for so long plus the original wear and tear. I've been thinking about resurrecting it, adding a couple more pieces for length, and re-lacing the whole thing with better quality lace.
