A few comments from me - if it needs a special ruler, I'm out - If it's all paper pieced, also out. What I will buy is something that I feel is unique. As an example, Elizabeth Hartman of ohfransson.com has several patterns that are interesting enough and just complicated enough that make me get out my credit card. If it's a simple block pattern, I will just figure it out myself. I've been quilting for just a few years, so it does not take very long to get past the "beginner" patterns. I actually don't even want to do them because there is no challenge.
