Jennifer, At the nature center where I work we have several exhibits which have braille signs. We also have braille texts (which may be borrowed) to enhance our vision impaired visitors' experiences of several exhibits. The brailled exhibits include our outdoor display of herbs and native plants and a "touch game" where objects can be felt but not seen. The signs are produced for us by a sighted volunteer who has a braille machine. She has to redo them every year because they do take a beating. Although we don't have many visitors who need to take advantage of these signs they are always greatly appreciated by those who do. You might want to contact a local organization for the blind to see if anyone is able and/or willing to do the signs for you at no cost.
