First you have supplies
Felt (white and coloured) or Ribbon (If using ribbon sealing the edges helps)
and of course Hair clips!
From there you cut the teeth. This is just a piece of white felt (I used a piece 1cm x 3 cm) for the size clips I'm using. How I worked out how much I needed was to simply clip the clip onto a piece of felt and cut around-
I then stuck the white squares onto the green, maybe 1mm in from the end.
I put glue along the topside metal and ran the felt/ribbon along sticking it down as I went.
You then need to open the clip up and fold the felt back in. Don't run the bottom piece along without having the clip open! Otherwise it will stick to the white felt. When you're done put something in the 'mouth' to keep it open (I used a match stick)
Next your eyes and rhinestones and put some of the glue onto a small piece of plastic and get a tooth pick.
You should end up with something like this!
