When I started experimenting with knitting with fishing line I also tried some crocheting and this piece was one result. It's been hanging around since then; not sure what it is.
Today, when it re-appeared in the bottom of a WIP basket, it suddenly looked like a – dah dah – button.
It's being left in full view on the table and my antenna are now out to see what garment would be complemented and complimented by such a decoration if not also a closure.
