...and a swirl! The magnetic snaps are in:
At first I wasn't crazy about the plastic outer ring that you sew through, but it does give the thing a lower profile and it has some flexibility. The magnets are very strong. Other than my own amateurish stitching-on, I am very pleased with them. If anyone else is looking for this kind of closure, I got them here. Now I need to start sewing them into some other bags, including my mom's - she left it here for me while she is off basking in the sun, lucky her :)
This one turned out better than I expected! It just needs a little brushing and off to the post office it goes. A little late for Christmas, but I'm very glad it's done.
