Many watercolour types have to spend a lot on sketchbooks, with the proper paper and all. I found these black spiral-bound books at Dollarama, and they’re pretty good for watercolour. I worry about the paper, since it probably isn’t acid-free. Also, it tends to break free from the perforations along the side rather easily. But for sketching, it’s great.
These are some things I’ve been doing during this time.
