I made a small batch of minute crochet jewelry for my spring/summer collection and though working with crochet thread and small hooks is extremely straining, I love the looks of lace jewelry made with thread, so the effort put forth was worth the trouble. 
I made these inspired by the Birds of Paradise flower (Strelizia) and there are several variations in both design and colors. 
This set is made of a pair of earrings and a necklace. The crochet elements are glued on decorative trays, which I was reluctant to try at first, but it seems that has worked out beautifully as well.
