Ribbons!

I am attending PenguiCon this year for the second time and I had thought of making my own ribbons this time around. Sadly, I am a few days too late to make my order with the Ice Cream Team. Then it hit me: print some of my own in Atlanta and bring them up.

However, being a dunce lately due to over-schooling and over-working, I am having an attack of Teh Dumb. What type of shop do I need to go to for ribbons of my own? What specific item do I need to ask for? If someone could help me find my words, it would be greatly appreciated.
