It's fabric, spray adhesive, a rubber rug backer. I folded over and hot glued the edges. I then applied two good coats of water-based satin poly. The result is a water-proof/ spill-proof kitchen accent rug that keeps my tile floor protected.
Anderson creates a custom rug out of green and brown remnant carpet. He cuts the pieces into various sinuous shapes and attaches them with carpet tape to resemble pathways running through grass. The entire piece is attached to a rubber rug grip with silicone glue and more carpet tape.
