I mentioned before that I really love Purl Soho and I also love the owners book
Its full of beautiful photographs and the projects are organized into categories of under 2 hrs, 2-4 hours, 4-6 hours, 6-8 hours, and over 8 hours. Many of the projects are too challenging for a not very advanced knitter like myself, but there are a few easy ones as well.
I made the Big Lace Scarf in the book for a Holiday gift and it did indeed take only about 3 hours to make. It also used only one skein of Cascade Magnum a relatively inexpensive yarn that comes in a wide range of colors.

Here is the finished project:
