I know I should probably just toss them, but the art student in me knows there must be some great use for them I just haven’t thought of yet lol
I save up thread, yarn and fabric scraps that are too small to do anything with in a shoebox, and then use it to stuff small pillows and such.
My current YouTube feed would recommend encasing it in epoxy, then using a lathe to make a bowl out of it.
Be careful. When a thread king gets to a certain size, it may acquire sentience.
In the crafting world, these are called orts. And some people get super creative with them! I’ve seen them user to decorate cards, to make collage art, to fill little clear Christmas ornaments or felt animals, etc. I’ve been saving the ones from my current project because I want to take a picture of the finished cross stitch next to all its orts. It feels like a visual representation of “you can’t make omelet without breaking a few eggs”, you know?
