Uuh, I might get yelled at for being to ghetto with my labels, but I just use painter's tape and a sharpieConsidering that my bottles are usually 10ml and I change labels fairly often, it works. And painter's tape withstands steeping in hot water pretty well, peels off cleanly.
I am ghetto also.
I just use a piece of paper and hand print on it, then cut it out and use clear tape. I like the painter's tape idea, that sounds even better! I just don't want to take the time to mess with fancy printed labels. I just get creative while making my stuff, write down what I added, cut it out and tape it on. If I like it I have the recipe right there. If I don't like it I peel it off and toss it. It isn't as if I am selling the stuff and have to look all professionally typed or anything. So ghetto it is for me.
