Well, I tried the horizontal, and honestly, I didn’t see any difference. I botched the painting but that’s because I was trying to get it done while hubby was out of the room. He wants his daily painting to be a ‘surprise’ when he opens his lunch. Good thing he isn’t picky about the actual artwork, though he does love it when I do up a really nice one. I need to practice the quick painting more often. I can draw them, but I always try to do too much with a quick watercolor.
