Hey Rev - I can supply you with a great deal of smaller sized pieces of Ultrasil if you're interested. I've got a lot of cut-offs from Tarps that I often use for stuff sacks - I'd be glad to send you a pile. Also, I can send some 1.1 uncoated, one calendared and one not, and some 200d Oxford, and maybe some more. I'll look through things.
PM me with address. I'll be sure to give exact specs on all the materials.
