rob has forwarded me a link to this: the zipholder!
Have you ever sat down to a meal that’s so delicious that you can’t stop eating? Sure, it’s not something that I do very often, but Thanksgiving dinner and those “all you can eat” pancake dinners really test my self control. It’s during these times that my pants always seem to fit a little too tight. Unbuttoning them always seems like a good idea, until I remember that the zipper will just come undone, leaving me somewhat exposed. However, a new scientific breakthrough may change all of that.
this is actually a very simple, clever solution. albeit to a problem that doesn't really affect me.
