I also use old cut-up blinds and love them. They are easy to see and read. I also plant regular labels under the dirt because some critter loves to steal tags. I use pencil and waterproof ink on front and back of labels. The pencil lasts longer outside, but they are about the same inside the plant room. I have also started using a white permanent marker on the outside of my pots. I learned to do this when taking plants to a local garden sale. It is easier for shoppers to see what they are getting.
