Some new folks here not likely to remember me...I was one of the original staffers, and plein air forum was one I advocated for and help create, then moderated many years along with other forums. Going back...we could find hundreds of threads of how to's, helps by so many generous souls...and if you are prolific eventually what to do with all the paintings sorta sneaks up on you. I wish I could snap a finger and resurrect some of those with so much useful information. But..I recently came up with one solution for myself and thought it might be helpful or useful.
This past summer I had my first burn pile...which didn't go over so well on social media, some thinking it is better to give work away. But, it was liberating, and I needed space. Canvases, panels, frames take up room.
I think about 8-9 years ago in one of our discussions, perhaps it was Marc Hanson that mentioned the use of Arche's Huiles Oil paper...and I have done quite my share of paintings on that. Very useful, easy to carry in a large pad, and I found spraying Krylon Conservator's Retouch varnish (also a suggestion of Marc's when I asked him)...on the paper just before using made it easier. The paper was so absorbative that it dragged the brush so much. The retouch worked its way into the paper enough, and then created some greater ease of painting.
Well...I was reading on social media, and in conversation artist Scott Christensen mentioned he was using a Kraft paper...called Thunderbolt, for studies. Since I just retired instructing art in the physical classroom...I managed the habit and discipline of painting...but contract time in the art room gave me no time to really market. I have several galleries, but I have had no time to visit, push, find new sources. Something I need yet to do...soon.
So, I have paintings everywhere stacked, in hutches, overhead shelves I made in an attached room leading to the garage...EVERYWHERE.
So...this paper, is 80# cardstock. I do not like painting on white surfaces because white being a cool color makes the slightest warmth in a color read warmer than it is...and you will find as the painting fills in, you have to go back and tweak and rework. So, I like painting on a neutral ground, or warm. The Thunderbolt is a warmer brown paper and is perfect in that regard.
I tape the paper to a board...spray two coats of Zinsser Bulls Eye Shellac (available at many hardware outlets, even Walmart)...let dry. Then just before painting I might spray the Krylon retouch varnish...but not always.
Here then are some images that will explain and I'll walk thru...
First the paper...8-1/2"x 14"
