Gosh, you all seem very shy about sharing your yarnybits :D
Fine, here's some of mine! On the odd occasion when the mood strikes me I like crocheting vintage doily patterns, but with sewing thread in bright colours and a 1.5mm crochet hook. These are all about 40cm diameter.
You can find loads of these patterns for free here: https://freevintagecrochet.com/doilies.html
