[AERNet] Corrigated Writing Board

[K Anderson]

I'm writing to ask about a writing guide that, if memory serves me
correctly, is called a Corrigated Writing Board (or Corrigated Writing
Guide).  It is 8-1/2 by 11 inches.  The board has raised strips that
separate lines.  A blank piece of paper is laid on top of the board.
Feeling the raised strips through the paper enables an individual to write
straight.

Now for the questions.  Are you familiar with this guide?  Do you know if it
is still manufactured, and if so can you tell me where to find it?

Thank you,
Katrina
