This sounds great!
I would be most interested in strings, same as zozee. Minimum of 1.5" x 7".
But, I will add that I'm a nut about using every last bit of fabric. I have sorted bins with crumbs and strings that are an inch or less, and have started cutting and stacking 1" squares. So, I'll trade with anyone with a similar obsession! Or, if you just throw those away anyway, throw them my way...I'll pay postage!
