Non slip fabric for socks
Hi I wonder if anyone can help me track down a supplier of fabric that has the tiny rubber patterns on it for making non slip socks? My mum needs socks specially made as we can't find a supplier of ones wide enough to fit her badly swollen legs. Mobility is a problem so need something that has just enough grip to stop her slipping and falling yet not so grippy that she can't lift her feet, something she struggles with in the best of conditions. Making the socks isn't a problem in itself. Thank you any link would be greatly appreciated. (Sorry I know this isn't a quilting request)
