Hi! I noticed you mentioned Crafty Caps - I just thought I'd let you know that we did order some from them a while back. They are adhesive labels/stickers, but they are sealed so well, they looked great for our party. We ordered some that had a black background, and ordered black caps with them...you couldn't even tell they weren't apart of the cap.
We are considering trying out the guy that uses the "lasering" technique though. Would like to get some different ideas to see what we like best!
Happy Brewing!
