Just in case you were wondering how (or indeed if) I managed it, here are the Button Push Pins all packaged up and ready to sell:
I used some polystyrene to stick the pins into, cut into squares, and I printed out an image of a cork board surface to cover it. The whole thing is then slipped into a cellophane bag (I get through hundreds of those things, in all shapes and sizes!)
I think they look pretty cool, and I sold quite a few of them at a Craft Fair on Saturday. Which meant I *had* to go to the button shop on Monday and buy some more!
