I'm not sure if that's the right word I'm searching for here but I'm sure a helpful MNetter with correct me if not!
I make jewellery and I have a product which I personally really like but I don't know if its something that will appeal to a wide market and if I should bother trying to sell it or if its something that only appeals to me and others that work in a particular area.
Obviously I realise that I can't really expect you to comment without knowing what it is, and this may out me but here it is:
Its a 'DNA' bracelet. Well, it looks like a strand of DNA, using pairs of different coloured beads to simulate the A-T/G-C base pairs and either leather or hemp cord. I vary the patterns of the beads each time I make one to try and make each bracelet unique 
Aibu to think this is this something people will be interested in? Or is it a bit too geeky to have mass appeal?
