I've seen lots of people doing really cheap badges at cons. Well I always thought they looked a little, ehh, not worth it really. Well here is what I came up with. For $1 I'll draw you a little stick figure like badge. They are not that big, maybe 3.5 x 2.5 and for $2 I'll laminate it for you. Oh you also get to pick what color ink you want used.

These are done on the spot, right in front of you.
