Vintage book paper has the best texture! It's one of the best things, I think, to water color on. I purchased one book from the goodwill ages ago and I am still using papers from it. As a reader the thought of ripping pages out of a book make my stomach flutter, and if you are like me and have a hard time doing it, look for a old children's dictionary. Those are so outdated they aren't really needed in schools anymore. The paper will be heaven!
I stamped outline image with staz-on ink and then I just used regular CTMH dye base inks and a water brush to color in the flowers with loose strokes.
