I swear I saw some round stick on labels for beer caps on eBay, but now I can't find them. Basically what I want is printer sheets with small round labels that can go on the caps. Any ideas?
I use these from Avery. You can get them at Staples.
Edit: For future reference, it's item #6103 in case they change their website.
Avery actually makes these labels and you can use their software for free! I found/bought them at Staples for under $10 for something crazy like 2000... and for $5 you can get 1200 colored labels!
I use the 1" labels myself.
