I really enjoyed the class. I was thinking it could be nice to have a photo of the scene to help visualize what we are painting. One thing I didn't like was how I couldn't get my fingers clean. Do you have to wash your hands during the process? I used a wipe but it didn't get all the pastels off. Any tips? I also didn't know how hard to press the pastels against paper - if I press too hard, it feels hard to blend; if I don't press hard enough, the color looks really light.
