Many artists use these Citrasolv papers as background for collages. If you don't know about this process a good video to find about about it is one by Cathy Taylor of Cheap Joes's https://www.youtube.com/watch?v=FskgfDxI__M The Citrsolv website is also a great place to check out what artists are doing with this technique, http://citrasolv.com/ Once there, go to Artist Support. Basically, you use a natural, citrus based cleaning product called Citrasolv, which you can buy online or at health food stores. You apply it to pages in a National Geographic magazine, shut the magazine, let it sit for 2 to 24 hours, then open it up to see the interesting results obtained through the ink being dissolved by the cleaner.
This last week I layered a photo of a shibori piece over a couple of my Citrasolv pieces, increasing the transparency of the top piece. This is what resulted.
Here is a photo of the Shibori piece. I did this with paint, rather than dye, something else I've been wanting to try. I rather like it, and it was much easier than using dye. The fabric is not quite as soft however.
Above are photos of the layered images.
