Using Citra-solv with National Geographic pages is a great technique for making collage papers. Paint Citra-solv to one side only of a National Geographic double-page spread, place the "wet" side face down on the the other page & rub the back a little. Use a heat gun to dry the back of the wet page and pages are ready in a minute or so. Peel the pages apart before they stick.
In the UK Citra-solv can be bought online from 21st Century Health - I get the large 32oz bottle, expensive but works out more economical in the long run.
