Above: A selection of journals I've made over the years with Strathmore Aquarius II watercolor paper. The two journals at the back right are sewn-on-the-spine constructions, the rest are casebound journals. The decorative paper for these book covers was made by me using watercolor papers and a variety of techniques. Click on the image to view an enlargement.
I've written several times about Strathmore Aquarius II watercolor paper, which is an 80-lb watercolor paper with a slight cold press texture. It contains synthetic fibers which keep it from buckling when applying wet media. If you have missed those comments on my blog and on Rozworks' journal selections area you might want to check out the autumn issue of the Strathmore Artist Newletter. (A download of the newsletter is available at that link.)
My article talks about the suitability of this paper for handbinding into mixed media journals. You'll see pages from my journals as well as some delightful landscape sketches from artist Diane Wesman who loves making quick, on-the-spot landscape studies in books made with this paper.
The article also includes paper tearing diagrams (you can cut if you really don't want to tear) for making signatures for two different journals: one portrait and one landscape. Use either with your favorite book structure case to make your own book out of this versatile paper.
I hope you enjoy the article and end up giving the paper a try.
