I Have a template for quilting that I got from my dealer. She used shelf liner and cut small, small pieces of the liner and attached to the ruler inplaces with double stick tape. She also stuck some pieces to the top side. That ruler holds steady as I quilt around it. The pieces of liner on the top keep my fingers from slipping.
I bought a roll of shelf liner at the dollar store. Just need to get some double stick tape and I am going to fix all my rulers and templates. just small pieces taped inspots will work great.
