You are welcome to the scraps from the piece I ordered.
1 scrap - !6" by 27"
2 scraps - 9" by 27"
PM me if you're interested.
BTW - this stuff is not a mylar-dyneema laminate like Cuben - something quite different, and not near as strong. But might work with mitts if sandwiched between inner and outer layers of more durable and breathable materials.
