Last week I used Citra Solve to dissolve the ink on tons of National Geographic pages. Since then I have been playing around with the pages and added layers to them. Some of the layers are added with acrylic inks, watercolor pencils, pastels, pens, stencils and stamps. Other's I scanned into the computer and altered in Photoshop. It is very addicting.
As you can see by the photos of all the pages lying out in the sun you can do a lot of pages in one afternoon. The Citra Solv is 100% natural but has a very strong smell so I worked outside with gloves and a mask the day I altered the pages. I left them to air out the whole next day.
I put pieces of wood over the pages so they would not blow away as they aired out.
