SBQ: What do you do with oorts?

The current Stitching Blogger’s Question is:
What do you do to your thread clippings? Do you just scrap them or do
you use them in something else?

I throw them away, as I don’t know what else I would do with them. The only possible use I know of is a vague memory of someone on RCTN using them to fill witch balls (glass fishing floats?). I’m curious as to what other people do with them, though.
