Everyone has such great ideas! I think I am going to have to try that rubber mat of carpet...I think my prob is there is a shine finish on my concrete...which makes the sliiiiiide go easily:)I have actually one of those round rubber jar openers under it. It is just like that rubber you use to set wet dishes on. Still slides! You should see all my activity to try pulling it back to place while holding my fabric in place to sew!LOL Now, I don't have any of those rubber backed rugs here....I think my mom has one in her guest bathroom.....you think she'd miss a piece?LOL I'd just remind her that the last guests could have taken towels like so many others....who knew they wanted a piece of her rug:)LOL Skeat
