MIke, yes, I have painted a couple of commissions on the Wallis paper. I mount it on Masonite with Demco glue, just the way I mount my linen.
I couldn't get small detail on a surface with much texture - the "sand' quality of the Wallis sanded paper is
extremely fine and uniform. The Claessen's L-600 is also really smooth, and of course, the ABS plastic is like ivory. And I like my little brushes
