I'd be afraid an iron would melt the jacket fabric. You could sew on a small embroidery patch, depending on where the hole is. Maybe scatter several tiny flower patches in a decorative arrangement. Another thought is to use fabric glue, maybe there is a place you could trim a tiny piece off a seam allowance and slide it into the hole, then glue it. Good luck!

If you have a small scrap of the fabric, you can use a fabric glue and put it on from the inside. If you use a teflon sheet you can press it without melting the fabric. But don't go very hot with the iron temperature.

Thank you Kim. Thank you Laura. Fabric glue..hmmm, didn't know there was such a glue. Well I'll find some of that and follow the advice. I very-much appreciate the help. Thanks
