I decided to devote an Art Journal to watercolor painting. However, I didn't have a journal with watercolor paper. And the nearest art supply store is over an hour away.
So I went to Walmart and purchased a Canson Watercolor Pad (140# weight). Cost was $6.00. (About a month ago Walmart was selling them for $5.00). I separated the pages from the pad.
Then I went to Office Max and asked for a spiral binding. Cost for this service was $3.52. For a total of $9.52, I now have a Watercolor Art Journal. I'm happy with the results.
