I recently got some Post-It Super Sticky Name Badges and decided to play around with a couple designs for making printable badges. If you don't want to buy a pack of labels, you can print it out on regular paper and use repositionable glue on the back. The PDF is HERE.
When my kids were babies I labeled *everything* I could in the house. The theory being that people refer the items regularly like the refrigerator and the television and seeing the word on the thing would help them associate letters to words quicker. People teased me about it of course, wondering if I'd forget what a door was, but I think it did help. I used masking tape and permanent markers. Repositionable easily removed labels would have been so much better. I'm not sure if anyone else can use this idea, but I did make a set of 8 labels with a few common household things on them.

The printables work with Avery 5395 or compatible.
