Random tangles, no string. The first tangle selected was Bumper, and I immediately used it as a frame. The next three tangles were Butria, Centepede and Kiss. I liked that combination. I added the Centepede first to break up the center of the tile. Next, the three Kisses were grouped together, slightly overlapping to fill the larger, right-hand space. A single Butria was added in the lower left to anchor the center elements.
