A very good light sewing awl can be made from a heavy sewing machine needle. Drill a hole slightly smaller than the shank of the needle in a piece of 3/4 dowel or other suitable piece of wood. Either use existing holes or make new ones. I've sewn lots of leather with one of these, and waxed dental floss is good. If you need black, use braided nylon fishing line (not monofilament) run over a candle to wax it.
