I like this!
Using the whole piece would certainly cause less scratches than cutting a lot of sections. My hands and arms are already decorated with enough road maps of thin scars from using this material!
The ones in your picture look brand new; have you stored them yet? Do you fold them flat and then fold them again to make them fit inside a storage building?
(Then again, I guess they could be walked on to remove the high points, then re-rolled for storage...)
Great idea...thank you!
