I forgot to mention in my previous post a very important tip when working with Prismacolor pencils. The soft leads tend to break and fall off when you use a regular pencil sharpener. I highly recommend sharpening your pencils with an Exacto knife. I learned that little trick in art school and I never sharpen my Prismacolors any other way. Just whittle a little bit away at a time until you get a stubby yet sharp point! I'll post some pictures tomorrow so you can see what I mean.
