Those sticky rolls that you cut to go under a rug to keep it from slipping. What do you use them for? Here are some of mine.
!. I cut for insoles and/or shoe padding
2. Use them in my van (vinyl floor) so groceries won't slip.
3. On my dashboard for sunglasses.
4. Hiking stick grip
5. Jar opener
They are commonly used for yoga, rolled up, in different colors.
There is also shelving material with a woven texture that I use on our boat to line drawers and stop things from rolling off the table.
The boat is 'not tightwad' however.
