These are perfect for the long arm rulers. I haven’t put them on my cutting rulers yet but I imagine they will do great there as well. They are very thin so it doesn’t raise the ruler off the fabric too far and they are just the right amount of sticky. They stay still but aren’t hard to move.

I haven't used them. I also work in glass. Do they work holding glass to paper and are they then still reusable after being stuck to paper?

Didn't know what to do about the stars, hope the TrueGrips work as touted so 5 stars would not be a lie!
