In January 3 of us got together at my house to paint papers. We'd paint part then pass it to the next person. This month we went to the next house and added to the papers with rubber stamps, pens, pastels, and stencils.
To this I added the rubber stamp spiral. It's one I made using kids' sticky backed foam on an acrylic block. It was cut with a decorative blade in the rotary cutter than curved into a spiral.
This is stamped in the green background with a plate I made from styrofoam left from the takeout box. I then inked around some of the small shapes with a silver gel pen. The silver one I seem to use over and over.
I have a commercial flower stencil that I use a lot-like flowers. Marking pens work well with stencils and don't make the mess paints do. However, when you wipe them off, more paint is transferred to whatever they are sitting on.
Marking pens through a stencil again. I was recycling old microfich film and cut the curves with an Exacto blade.
