I have used silicone caulking on the backs of a few rugs. I didn't make them; just bought a few for in front of the kitchen sink etc that were not backed and slippery. so, I got out the tube of silicone caulk I had for around the tub and squeezed thickish strips about 2 inches apart along the length of the rug. let it dry over night and works great.

I was thinking of something else, though. An aunt (now deceased) gave us some t-shirt decorations made of needle-punch (like a rug, made with yarn). She sprayed or spread a product on the back that allows it to stick on the t-shirts, then taken off and stick on something else. It won't stick any more if it gets dirty. I think it was a product made by Alene. I looked for it in stores and I was never able to find it. Maybe someone else knows what it is.
