I took a couple of sheets to a framing shop while I was getting a pastel piece framed. They mounted it for me onto gatorboard. I always work on a hard surface so it did'nt take getting used to.
What you will need to get used to, is the how grainy the Wallis is. You'll use up a stick if you're heavy handed. If you blend with your fingers, expect to lose some skin.
You can do a search for mounting techniques, I know I had seen something a while ago.
Good luck.
