Sorry the pics are bad quality, I made these at night and my camera's flash wouldn't work. This is my first ever how-to so sorry if I'm a bit confusing
First, take one colour seed bead and thread them through onto one eye pin, leaving enough space to make a loop at the top.
Put the earring hook onto the top part of the eye pin and use pliers to bend a loop.
Open a split ring and put it on the other end of the eye pin, attatching the key to the earring.
Repeat this with the different colour of seed beads and attatch it to the earring hoop behind the one with the key and attatch the heart to this one...
And you're done. Enjoy =]
