I have 2 Quilter's Select that was given to me and the woman had stretched clear contac film over the bottom to prevent the info from coming off and told me I would regret it if I ever pulled it off. Well I have never pulled it off but I do nt use them either as with the contac on the bottom they slip and slide all over. It is very difficult for me to keep the ruler in place so I went to Dollar Tree last year and bought several aluminium rulers that have the cork on the under side for a buck a peice and those are what I have used exclusively this entire year. They are the best I have foun for making straight lines. The cork stops the ruler from slipping even on true satin fabrics. I don't plan on ever going back to the Quilter's Select.
