I stumbled upon a fun watercolor tutorial last week and tried it out- and I must say- I loved it!
Try the Watercolor Cactus Painting Tutorial by Inkstruck Studio. It's a good way to have fun and loosen up with watercolors. I made two little 5x7 cactus paintings in pink tones.
Then, since I was in a cactus-painting-mood, I painted a potted version and outlined it in ink.
