Fasten one end of your thread to the snap hair clip with a tight knot. Cut the short end so it's hidden behind the clip. You can also use a blob of glue to secure everything to the clip.
 Twist some brass wire around the thread where you want the first beads and feathers to start. Twist it very tight around the thread to make sure it won't slide down when you put the clip on. Form a little stopper for the beads as you twist. When you are ready, get your beads and make sure that the thread and the wire are going through them.
 Next, place two ore more feathers into the last bead. Secure everything with another wire-stopper, but this time you twist the wire around the thread and the feathers, securing beads and feathers in just one step! Cut the wire and hide the end.
Leave some space and then repeat the whole process further down the thread until the feather clip reaches the desired length. The clip looks lovely if it's slightly longer or if it's shorter than your hair as well! Try creating a few matching feather hair clips in different lengths or knotting more than one thread to your clip for a more "feathery" look.
