So far, I've found the Single Patch pattern to be the easiest. Yet in the book I've been learning from, had the Four Patch pattern before the single--the single is SO MUCH QUICKER! haha, if you want a quick accomplishment, google search it, I can't imagine it being a pattern you'd have to pay for!
I have a picture of both on a post "my UN-finished projects" under the pictures area.
