Was in a quilt shop talking to the owner.We were discussing ruler & templates slipping as we use the rotary cutter. She took us to her work area & had a template, moved it around on her fabric, turned it over & that thing would not budge. She showed us, she had sprayed a light coating of 505 basting spray on the back. What a great way to hold the rulers down too. In order to remove the spray she uses goo gone. She also keeps her templates in zip lock bags to keep them clean when she isn't using them. I want to spray all of mine. I was truly impressed. I know you can use the dots,sand paper etc. Any one ever heard of doing this?
