We once went to a summer camp called "Mindstretchers" at a local college where we stayed in the dorms and instead of boondoggle and archery, we took classes like...logic and sign language. It seemed very grown up at the time, but looking back we suppose it was kind of dorky. However, we still remember most of the American Sign Language alphabet and think it's a good idea for everyone, even kids, to know a little, even if just to spell your name as introduction.
Portland artist Sarah Landwehr agrees and has made both an American Sign Language poster and individual letter blocks so more people can share and learn this beautiful language. Her ASL alphabet poster is screenprinted onto 14" x 18" oaktag (similar in color to a manila folder) in red and black. She sells the posters for $40 or, as incentive for teachers to bring ASL into the classroom, at a discount of $25 for teachers.
Sarah hasn't made all the ASL letters into blocks yet, but she's working on it. They're screenprinted and tea-dyed before being affixed to a painted red wood block. Each block if finished with beeswax and resin and costs $10.
