I was at first going to skip this question because I "just know" I don't have anything at all odd in either my handbag or wallet. Then, though, I remembered that I do have something strange: It's a piece of purple curling ribbon, wrapped into a coil, and fastened with a piece of Scotch tape to prevent unraveling. It's in a coin purse.
Why I have it is that I cut it the exact length of a door shade that I've been wanting to replace, but that's been hard to find. I coiled it because I'm a neat-nik and don't want to have a big, unraveled, piece of purple ribbon getting in my way when I go to get something from the bag. Also, curling ribbon curls if it isn't wound up, and I don't want it to be curvy when I need to have it used to cut a shade.
The trouble is, because I stashed it safely in that coin purse I don't use in order to keep it in good shape; but I keep forgetting it because it's hidden away in that coin purse. (By the way, the coil is about as big as a quarter. :) )
So that's it - a coiled up purple ribbon with tape on it. :)
