Definitely a log cabin, but you'll need a couple more darker prints. It's a great block to use those fabrics with. Be sure to leave a diagram of the block in front of you as you make it, though - its easy to pick up the wrong fabric and have a dark where a light should be (or vice versa)...
I'm working on a large king size version now -- my strips are 2.5 inches, which makes my blocks 18" finished. It's autumn colors mainly on the darker side and white/offwhite/beige on the lighter size. Wanted a larger block as it will be 120 x 120 when completed.
