If I could leave you with this, if you are going to watercolor, use watercolor paper. Using cardstock, even the heavy duty (110 lbs weight) is not suited to be used with water. I have only used the ones mentioned as well as Tim Holtz watercolor paper. I am certain Canson and Arches paper are fantastic, but I am very happy with Strathmore.
I am very excited and pleased to present my first video on this topic. I would be tickled pink if you would subscribe to my channel. If you found it helpful, a thumbs up would be great.
