I don't have the gel mat but picked up some of those rubber mats that look like a jigsaw puzzle. I placed them along my quilt frame as its all concrete there. My cutting table is in the other room and though its concrete under the indoor/outdoor carpeting I don't seem to need it as much. Also think the previous owners glued 2 layers of indoor/outdoor carpeting on that side of the basement. Hate indoor/outdoor but just never got around to replacing it. Wish I had now but too much trouble replacing it with all the stuff I have in my sewing room.
