Well you need to cover the cost of your time and effort - I don't know how much time went in to making the blank but I'm guessing it wasn't knocked up in an afternoon. If you think you can at least break even at £7.50+P&P then great for us, but I'd be happy even at £10+P&P, especially if they're securely packaged in a tube like the ones Luke just posted
I'll definitely be up for a couple - possibly more, but I wouldn't want to hog them if there are a long list of interested buyers.
