I've also used beer labelizer.com for many of my labels. I made the mistake of using pre-gummed shipping labels on my first couple of batches - don't, they won't come off with any amount of PBW or oxyclean. Those bottles all ended up in the recycling bin. On advice from wiser brewers, I now thin elmer's glue in water and use a brush to apply. They drop right off in warm water during cleaning.
