I hadn't considered that, thanks for the advice @Dravis

As I've already purchased the starter pack and mould kit I dont want to buy any additional CF at this stage, just incase things dont work out.

After some consideration I'm going to scrap the idea of a phone case until I know what I'm up against and working out the best way to reproduce it.

As my main interest is the automotive industry I think trying a small car part may be much easier..

I will have a butchers what I can find, post a picture and get some opinions on how to best replicate it in CF before I make a move.
