I've had a client for 2 years now who is legally blind (Im not sure what her percentage of sight is) She is able to see a bit but isnt very mobile, everything around the house is outlined with white paint. Anyway she sends me cheques that are about twice as big as a normal check with extra big lettering and braille. Should I send her invoices with larger font? Would it be acceptable to this? Anyone else have a blind client?
