8x16 inches - pastel on museum board with Golden pumice ground
Another painting based on the drive back from the Needles Overlook, along the road of the same name, which I just can't seem to get enough of. This one made a perfect crop to a 1:2 format.
It's hard to tell from the photo because I employed blending here, but this is on a black-toned surface. I usually mix acrylic paint in with the pumice ground, in an approximate 1:1 ratio and add a small amount of water from a spray bottle. One or two layers and it's good to go, and because the board is smooth, the only texture I have is what I want: from the pumice grit. It's particularly good if you frame without a mat.
If I frame this one, I will probably try mounting it on top of a mat (since it isn't in a standard size and I can't afford to custom frame anything) with archival foam tape. I've seen many pastels on paper with deckled edges framed this way and I like the look.
