Party Pennant Banner ($22) on Etsy. Ideal for a race car fan. I'm keen on the colors.
If you are the crafty sort, I found this step-by-step tutorial to make your own banners on Miko Designs. Looks like it is a project that doesn't demand a high level of sewing skill.
How about the details on this floral design? Carnival Bloom ($30). This one is so pretty I'd have a hard time taking it down when the party is over.
