You don't always get a chance to dress up for Halloween, say, if you're stuck at work that day, but you'll still want to get into the spirit of the day. You need something, not a costume, but something to show that you are still celebrating this important Maker holiday.

, and a handful of spare eyeballs have spent the year sitting in my shed.
Coming across the spare eyeballs, the Hallowe'en Pin Badge was born.
