I have so many unlabelled bottles it isn't even funny. I use things like rubber bands twisted around a bottle meaning sweet, no rubber band meaning dry, etc.
How do you get your labels made? Can you just buy blanks, load them into your inkjet and easily print them out? What kind of software do you use to design them? Hopefully something free like OpenOffice or the Gimp?
It couldn't be easier! I have Avery's free label prgram and use Avery's 6/sheet laser labels. All the clipart was included with the program. You can download it from their site I think. It is called "Design Pro". As an alternate, you can use MS Word. Also those labels are pretty easy to get off in the sink. Most just float off after a 10 minute soak.
