I have a few sets of Grog tag labels that I got as a birthday present a few years ago. One set for my standard house lager, and a few more generic ones (Ale, Lager, Craft Beer). I don't bottle as much as I used to, and when I do it's my lager for my family, so I don't use the other ones as much as I'd like.
I more often print off paper ones and stick them on with milk. I do this around Christmas when I bring bottles to share at family gatherings.
As for designing, I use Bluebeam, which is not really a photo editing software. It's a PDF markup software that I use for work, but it's free/available and I know how to use it.
