Someone asked me about the resin-coated paper I've been using. My goal lately is to paint, paint, paint as much as possible. Being as "frugal" as I am, I was looking for ways to cut costs. At Judson's (of plein air art supply fame), I may have found my answer. This is tan-colored card stock that has been sized with resin.
I found it a bit too slick for knife work, until I added a coat or two of clear Gesso. It's just fine for brushwork. They also offer a very reasonable multimedia art board. I haven't tried that yet, but it's on my list.
