I was amazed in my first class with Eleanor Cox when she used artist's tape to attach fresh paper (un-soaked) straight to a thick foam board called Gator Board. This thick white foam board with a plasticized surface comes under different brand names, one of which is Elmer's brand. It is lightweight and waterproof. Paper can be attached with tape or staples or push pins. Here is a link to the artist's board offered by Dick Blick: http://www.dickblick.com/products/incredible-art-board/
I have begun to use it for virtually everything. I watercolor or paint with pastels or use gouache on it. I usually staple the paper to it as this allows a person to work to the edge.
Recently, I have covered the edges of the board underneath the paper with artist's tape. This eliminates much clean up and helps preserve the board (which is not inexpensive).
Give this board a try. I believe you will find it worth the price.
