Strings for me. I keep a basket for the "droppings" and when I get quite a few, I sit down and sew....Mindless and relaxing. I buy the foundation papers at Costco.....the waxed sandwich liners. Cheap and always handy.......I usually make piles of 10 and then pull the papers off in the evenings, watching TV. Doesn't take long and again is mindless and kind of fun!
