I decided to give a try to the "Stencil Monoprints" card on Splitcoast Stampers.
The idea is to ink up a stencil, spray it with a little water and apply the dampened stencil to watercolor paper. Gently pat the watercolor paper with a clean rag to soak up excess water/ink (I did try this several times and it does take a little experimenting to get the hang of it.)
I had a smaller stencil than the tutorial, so I cut it down to the size of the stencil to apply it to the card.
Here is today's card:
