Coloring Rubber stamps with pencils

With the rise of popularity of Magnolia stamps, I got curious about coloring stamped images with pencils. I'd heard about Karisma and Derwent pencils from scrapbook forums before, but never got into it much. The other day at a crop at Scrapware one of the ladies there, Ingrid, showed me how to color a stamped image using pencils and odorless solvent . The result is the christmas mouse on one of the christmas cards in the story below. She used Koh-I-Noor pencils. It got me thinking about it, and I dug up my big box of Bruynzeel Fullcolor pencils. I got this box from my parents of 100 quality pencils years ago. I didn't use them all that much, enough to lose some but not enough to have used all the colors by now. I started to wonder if these pencils would do. Some searching let me to the information that they were pretty good pencils but also discontinued.

I also found this tutorial in dutch and english by Inge Groot who works a lot with Magnolia stamps

So I went out and got me some odorless solvent and paper stubs and some nice cute stamps to try out my Bruynzeel pencils. Here are my first attempts. What do you think?
