I had another Wax Day the other week, with Jeri MacDonald (as soon as she gets her web site updated, I will post a link). I love working with encaustic on paper. This is 300# hot press watercolor paper, Arches, I believe. We both work with encaustic medium, a few colors, oil stick or pigment stick, and a bit of oil paint. Here are a few of my 5"x5" pieces:
The pattern of circles on the left is incised with a stylus while the wax is warm. Incised lines on the right, the dark ones, are rubbed with oil paint.
This one is probably not finished, well, definitely not finished. Not sure where it will go next.
The color in these that looks like Qinacridone Gold (an acrylic color) is Alizarin Orange. I have it in encaustic paint and oil paint.
