This technique is super easy, super smelly, and can be super messy! LOL
First you need a bottle of CONCENTRATED Citrasolv. It is a natural cleaner/degreaser found in the grocery store or co-op food store. The one I found in my local food co-op smells like oranges. A 16 oz bottle was about $10 US. It also comes pre-diluted in a spray bottle BUT DON"T BUY IT, CUZ IT WON'T WORK. You have to have the CONCENTRATED formula.
Second you need a National Geographic magazine LESS THAN 10 YEARS OLD. I don't know why, it's just what I read. Must have something to do with the inks?? GO OUTSIDE or SOMEWHERE WITH GOOD VENTILATIONPour some of the Citrasolv in a dish and use a paintbrush to spread it on the pages of the National Geo magazine. On the one I used I found it did NOT work on the cover or the first few and last few pages of ADS in the magazine. Just brush it on the front and back of all the nice COLORFUL pages. Leave it all closed up and let it sit for about 30 mins to 1 hour.
Check it after the first 30 minutes just to make sure it's still wet enough that the pages are not sticking together. Peel a couple pages apart and see if you like the result. When they are as you like rip them individually from the mag and lay them out to dry. I just laid mine all over my patio.When dry they are ready to use. You can't tell really well from my photos, but they'll have sort of a shimmery appearance. Very easy and very beautiful technique for backgrounds.
