Just go online and get yourself 20 or 30 feet of black 6 mm nylon assessory cord. Cut yourself 3 foot or 40 inch lengths, try it out to see what length is right. Tie an overhand knot with three or 4 inch tails, weld it tight, loop it over the stand-off on the bottom of the stick, and tie another knot to hold it in place. You can experiment with placing the top knot off to the side, in order to avoid the knot being between the sticks when you stack them.
You’re done, and this is lighter, easier to pack and a lot cheaper than any of the store-bought solutions. You can slide it through an 8 inch section of 11/16” tubular webbing, or any of a dozen other things if you want something to keep it open for your foot.
