After watching an awesome episode of Dr Who Series 3 (Fear Her) with an really inventive alien (the Isolus) I really wanted to make one. I thought it would make a great Brooch.
It fitted in with a HPKCHC subject on Ravelry so I crocheted one up. Honestly I think it is too chunky and heavy looking so I will probably make an organza/cotton sewn version...eventually
