A friend of mine got something like this for her birthday, and i thought “i could do that!” i beaded a bead onto three feathery bits at a time, and then i ran a tiny line of hot glue along the back of the beads to hold then in place. this is so much easier than it looks!
The birds nest one is a copy. here is the link just so that you can see the nicer original versions. http://www.sarahortega.com/2011/05/diy-bird-nest-necklace.html
The other one is original, but hard to see due to bad photography.
