For Christmas I made the tiniest crochet snowflake earrings for my Mom and sister. The pattern I used can be found here. Please note it uses UK terms (if you read dc in UK terms, make a sc in US terms). The real challenge with these earrings isn't the pattern, it's working with tatting cotton. I used a magnifying light to help me see and save my eyes. I also stiffened them with some glue and water while I blocked them, and painted them with a light coat of sparkly nail polish to make them shimmer.
