I don't know what a skullette is (a girl skull I guess?) but my daughter insists that's what this is. I found an image online and used my friend Jin's amazing tutorials here to make it into a cuttable file. I used my cricut and MTC to cut it out. My Monster High-loving daughter is thrilled with it! I feel like I passed some cool parent test or something.
