I love creating earrings, because they are close to instant gratification! You can start a pair in the afternoon and wear them that night.
If you've never done bead embroidery, earrings are a great start. If you've done it before, you'll still enjoy the designs, from basic to WOW!
I saw some beautiful jewelry and the owner told me she had made it herself. From that point on, I have explored just about every beaded jewelry technique I can -- bead weaving stitches, loom weaving, stringing, bead crochet, wirework...you get the idea, LOL!
