1mm Woven Merrowing Patch comes with some fabric glue from a craft store. Put a little bit on the back of the patch and apply it to the fabric. For the best results leave it be for at least an hour, so the glue can set. Once the time is up you need to test the edges by lifting them. 1mm Woven Merrowing Patch is a patch done by stitching a design with threads into a piece of fabric.
