Tabletop Ironing Mat 1 "Leaves a pattern on all you iron!" Mary 02 April 2014 Bought this to use in my sewing room. I took it back because it left an indented square pattern on everything I ironed. The pattern won't come out where I ironed interfacing to my garment!! A terrible product. Wanted to leave no stars, but not possible. A note from the team Thanks for placing your review. We're sorry that the mat hasn't worked for you and will be in touch shortly.For future reference, the review process will accept one star as the minimum score as the overall total of stars is then divided by the number of reviews to give the average score. The system will not accept zero as a score.
