Don't & won't patch jeans. However, I will repair GDs dresses. I was sewing a seam back together & the youngest at 4 years, was standing behind me. When I told her I was finished, she said "I'm finished too, Mimi." I turned around and saw she had printed her name on the wall! Guess what - it's still there, 2 years later!! I did take a photo of it! Love those grand kids!!!
