Here yet, is another way to "test" different papers. I taped down different kinds of watercolor paper and painted basically the same scene in a similar fashion to get a feel for how the pigment takes to the paper. The top row was applied wet-on-dry whereas the bottom row, wet-in-wet. The types of paper are labeled. You can keep then keep your "tests" as a handy reference and reminder of the qualities of each support. And/or they can be cut and given as quaint little ATC's! Have fun experimenting.
