A few things I wish I had done a bit better with the kids: Really emphasize to press down, maybe giving them a scrap piece to practice with. Many of the kids drew really lightly and myself and another mom went over their drawings again (shh. don't tell them!)
We were a little pressed for time so I wish I could have monitored a little better what they were drawing. I have a few repeats in there and a few pictures I really wish I had instead.
