A friend ask me if I could put a zipper in a tote bag she had. She was going on a trip and really did not like the button closing it had. Well I hit the internet and found an easy way to do it. It came out great, with a few minute fix. Here it is before I took off the button and loop fastener it had.
Here it is with the zipper in the top. I left it open a little so you could see the zipper better.
