I'm on a committee for a community garden and so the public often wanders in and wants to know what we are growing.So far we have a haphazard system for labeling plants, such as plastic tabs, popsicle sticks, ect. (Of course, some things are not labeled at all!) Does anyone have any suggestions for attractive, inexpensive and waterproof plant labels? Also, we need to make signs to explain some of our special projects. What would hold up well outdoors? Thanks!
