Someone posted a question on the Alteredbooks webpage asking about using a particular type of shimmery watercolor paint. I loved the look of the colors and went searching myself. I ordered from Jo-Ann Fabric & Crafts something similar to the kind the poster was inquiring about, simply called Pearlescent Water Color Set. Here is the first attempt at using them. I love the look of the colors - the shimmer is more subtle in some colors than others. I'm looking forward to using them more often!
