I've been planning doing some roller paintings for several years after seeing Brion Gysin's roller paintings.
I bought a couple of foam rubber rollers at Dollar Tree sometime last year and just this month finally put some paint on paper.
They came out very well, I think. I've purchased a couple of Speedball brayers and will carve patterns on them in the next few weeks. I also have several large 6' x 6+' canvases to work on.
