I've been looking for something similar to this! I have a pair that is a little more elaborate from a small boutique store and I've been dying to try and recreate, but I'm not sure of the best materials. Thanks!
Hi! I'm reading your message now! This project was an "experiment", so I used an unexpensive wire, but... the quality was so good that the earrings are still the same today, after much time! For the hoop I used the Beadsmith craft wire non-tarnish (0,8mm); I bought this type: http://www.enchantingbeads.com/mm5/graphics/accessories/1780h.jpg For the grid I used the same quality wire, but the size was 0,3mm. If you want you can hammer the hoop. The effect will be good :)
