This was an experiment a few weeks ago using matt board as the base.
Part of it was discovering if I could texturize regular paper like I do yupo.
The answer is yes. The base textured color here is blue, texturized with a dry cleaner bag.
The rest was done with stencils, just like I do on the yupo. It is hard to see here but I was pleased that the background texture under the white, beige and grey shows quite well.
This is my "dump" from last week
