I'm just about finished with this afghan. This is the one I made the center from some squares that came with some yarn I picked up at a thrift store or yard sale. I only have the ends to weave in. I'm not sure why the edging is "ruffly." I made it a little different by putting 2 rounds of sc before I did the shells--I won't do that next time. All the yarn I used was leftovers from other projects.
