While in the hospital, I managed to join a couple of craft workshops. I made these (among other things, I drew as well) with Mod Podge (some kind of finisher or glue). The design comes from a paper napkin. Then I painted the sides to match the picture. It's hard to see it in 2D. But it was done on a regular (square) paint canvas.
It was the world's easiest thing to do, but I messed up the "riesling" one - you can see bubbles/creases that are not supposed to be there. The activity was soothing though. I guess that was the idea.
