Home made scatter rugs. Just posting for your information.
I just purchased a couple cotton braided scatter rugs for our entrances (where they get the worst dirt and grime) and I can wash them in my washer and dryer. The lady said they don't slip on the floor, however once I got them home, they in fact they do slip - solution - the rubber cupboard liners, we type use in our Motorhome and purchased at WalMart.
I cut one the length of the scatter rug, then laid it on the floor under the rug, and now they stay in place.
