My friend at the the yard swears by her non slip mesh, says it's exactly the same as the one Bettina Hoy uses but cheaper! She buys it from Ikea it's non-slip mesh that you put under rugs to stop them sliding. It's only a couple of quid for a roll and you can cut it to size. I'm not convinced but then again I've never seen the proper stuff close up to comment.
racing people have been using them for years so nothing new about them just eveyone else is now realising why we ue them, as they do no slip. Try to get a racing one and dont wast your money on the big brands, IKEA idea is great
