Last year I was asked to make a bowl for holding yarn while knitting. Something to hold the thread in place would also be good. I designed a bowl with a rim that ended in two curly horns that one could easily pull a thread through, simply by pulling it to the side and up
I also added the nickname of the recipient to the outside of the bowl in raised letters, made as in one continuous thread (except the dot over the i).
If you want to 3D print one yourself, I’ve made the model (without the name) available for free here: https://www.thingiverse.com/thing:1312595
