I just clicked and saved nearly every pattern they make....then turned them black&white and compared the patterns to one another.
I'm sure they'll all work just fine, but I am real impressed with the Hawthorn Hideaway, Morning Sage, and plain Gray. I think they're tied for first place.
Evening Stand Green, Shadow Plaid, Buffalo Plaid, and Standing Timber Gray are all tied for second place.
I currently have Northern Lights. Not bad, but pretty dark overall. Maybe I need a new one in a new patter...
