I also made a pair of earrings for my mother this year. Using cotton sewing thread and a size 11 steel hook (1.1mm), I slightly modified the pattern for these earrings to come up with the ones pictured below:
What did I change? I’ve been crocheting for nine years now and I still can’t make a passable looking picot. So instead of 1ch, 3-ch picot, 1ch for each point, I chained 3 and then did an sc in the side of the previous sc. Seems to have worked well enough although the points could be pointier, I realize.
