Liquid Invisible Stitch Repair Adhesives lets you mend unsightly tears without manually stitching. It works on heavy-duty materials that have flexibility, such as leather, vinyl, and canvas. Because the adhesive material is waterproof, it creates an impermeable barrier on ripped tents and other outdoor surfaces. Simply apply a dab of Liquid Stitch to the edges of the hole, and it will mend the area as it dries.
