Handwriting without Tears uses grey block paper as a part of their writing program. For many of the kids I work with who have autism, grey block paper does not provide enough of a contrast for them to see the borders of the squares when writing letters. With a Photoshop-type program, I have created a white squares on white background. I use dry erase crayons and a reusable pocket called the Write and Wipe Pocket (available at Lakeshore Learning) as it provides a lot of resistance when writing and saves on paper. I also sometimes use blue painter's tape to provide a tactile cue for stopping at boundary lines.
