I bought design wall felt before I think from Fons and Porter. It was treated so that fabric would stay put. Eventually the stick part went away. I contacted the manufacturer and a person I talked to said to spray it lightly with quilt basting spray and it will be like new. I now have a bigger wall made with insulation board covered with low loft poly batting. I spray it with basting spray and never use pins. I respray when the tacky goes away about once a year. The lint and strings come off easily with a lint roller.
