After doing the drawing Entopic Graphomania exercise I thought it would be fun to add the same kind of technique to a finished piece, but instead of using pencil, using thread.
I took two finished pieces and stitched right onto each, using dots to connect my lines of thread.
For the first piece the paper was thin enough that I didn't need to use an awl, just the needle I was using to sew with. For the second piece I used an awl to make my dots, being that it was an encaustic painting and a little thicker than paper alone.
This is a very enjoyable way to add an interesting look to a piece of work.
