How do you sew patches on elbow of shirt? Package says to back stitch. Thats fine, but I am worried about the edges of the patch. It is a suede elbow patch with holes already there for sewing, but there is about 1/8 edge, will edge fray or turn up or anything if it is not sewed. Or is the suede more durable. As you can tell I have not sewed a patch for a while. This is for a friend of my husbands. I want to do a good job, I do know how to backstitch, but concerned about the edge that will not be sewn. Any suggestions?
