I recently learned that an SBQ is a stitching blog question, and I like this one: what do you do to your thread clippings? Do you just scrap them or do you use them in something else?
I was delighted when I learned that the common name for thread clippings was "orts." What a fun word! And I chuck 'em in the trash. I'm not sentimental about them. I use a small plastic Darice box to kit up my current project. If I have room, I stick the orts in one of the sections.
If I don't have room (HBP with lots of floss), I use a small plastic cup that I've elegantly suspended with clear packing tape that is held in place with my stone drink coaster.
When I'm done with my project, I unkit and throw out the orts.
