I tried both Yupo and a very heavy vellum. The vellum seemed promising but warped after it was wet (top right piece). The wrinkly one was made with a funky little punch tool, and I rather like it, so will make another but in Yupo.

I did extensive experimentation with both punches and cutting my own. The lines, the boxes and the flower stems were all cut by hand. Punches are limiting since they can only get reach so far into the page. 

All of the above came from templates, but I was happy when the little postage stamps looked cool with a little punched line in them.

In some cases, I kept the punched pieces like the tulips and vine which I might be able to use for some negative spaces.

I made three small try-out pieces The top was first because I couldn't wait to see what the stamps with little stems looked like. The warped vellum stencil is in the middle position. Another issue I encountered was that watercolor paint seeps under the very thin stencils. I figured that out when I worked on the last piece and my stuff smeared like crazy. So, I let it all try and tried again with acrylics, but it was still too wet. Lessons learned. The hand-cut set of curvy boomerangs were sponged with acrylic paint and didn't seep or smear.

Stamp pads, small ones, worked fine too. Watercolor was an easy background as long as I'm patient about drying. 

Thanks to all for sharing. Seeing other students' art is a great part of being in a class. Denise, this  class was valuable and challenging. The end results and future uses will be super-satisfying to have made them myself. 

Keep stenciling!
