I worked with Aunt Lydia’s Classic Crochet (size 10) cotton, but any material which suites your purpose is just fine. I added a few beads to make the earrings look even more interesting, but the beads are optional.
There are pictures to help guide you through the crocheting, and supporting the written pattern for these earrings.
I’m also confident that this written pattern is suitable for a dedicated beginner as well.
