Forgot that my grandmother would also take a home-made patch and put it on the inside, then put the iron-on or another home-made patch on the outside, and stitch around everything by hand. She was trying to make a really sturdy patch that would hold up for a while. We lived in the country, were outside constantly in the garden or the woods, and were hard on our clothes. There really wasn't money for new clothes, and she and my mom both repaired anything they possibly could.
