These post earrings are so simple and pretty, I can't wait to make a pair. The Free Spiral Post Earring Tutorial is available for download from Gailavira Jewelry on her website. She has several other tutorials on her website - some of which are free and others that she charges for. Her work is fantastic, and judging by the quality of this tutorial - I imagine they are all well worth the money.
They use 4mm beads in the center, 2mm beads to frame the center bead and 20g base wire with 28g coiling. They don't look like they will take too long to make either. Instant gratification and free - how much better than that can you get?!
