Still life with Pumpkin and American Flag: Step-by-Step Demonstration by Veronica Winters. Veronica uses Prismacolor Premier Colored Pencils (not Verithin) to create her realistic drawings. She says other pencil brands that are either wax based or oil
based are OK when following her tutorials. Her instructions are well written and, if you're interested in learning to use colored pencils as I am, I would highly recommend her book described below. It's one of my favorites on this subject and gets many positive reviews.
There is also a Kindle edition for $7.99
