The image, North Woods Stack, is stamped on kraft colored cardstock in black Memento ink and colored with Prismacolor pencils. I used Gamsol and a paper stump to blend the colors. I used a white gel pen to add white highlights to some areas. Pretty simple!
If you would like more info on this technique, I have a short Prismacolor & Gamsol tutorial on my Tips & Tricks page. The images in the post have been replaced with links (THANKS to Typepad - groan), but if you click the links the images will display.
I wrote the tutorial almost 3 years ago, and it remains one of my most popular blog pages. It's worth noting that Memento ink was not available at the time I wrote the tutorial. Now, I mostly use Memento ink with this technique, although StazOn does work nicely. You just need to be careful with StazOn, as it can bleed.
