Good old Martha taught us that rather than buying those ridiculously expensive anti-slip mats for a rug, just turn it over and run a few lines of acrylic-latex caulk every 6 inches or so. Let dry and flip over and your rug wont be going anywhere!
Another pinner said: I wish I had seen this years ago!! Tape before caulking. Smooth out with finger. Then peel off the tape immediately, before it dries. - Click image to find more Home Decor Pinterest pins
