Since we're supposed to get rain for the next few days, curtesy of Isaac, I decided to play with the CitraSolv technique today. This must be done either outdoors, or in a well ventilated place (I used my garage with the door up). I've been researching this via YouTube - but you never know what you'll get till you try it! I learned that it needs to be on longer than 20 minutes, and if you can't separate the pages - and leave them alone till the outsides are dry, you get another interesting effect on the middle pages -- it turns very pale with a lot of big white circles! Anyway, here are a couple of before and afters for you:
Two page spread before
Beautiful and colorful before
And after - it still retains the color, just not quite so bright.
I also saw on YouTube that nothing else does it - you have to use CitraSolv. If you live in a large city, you can probably find it in a health food store or Whole Foods - but if you're like me and live in a small town, you will have to send off for it through Amazon.
