This is one of my favorite quilt patterns, and yours is very nice. As for quilting, I had the same question when I recently finished a storm at sea. Hadn't even thought about how I would quilt it until reaching that point! What I ended up doing was a google search for images of that quilt, and it came up with a ton of peoples storm at seas. Not only was it fun looking at everyone elses color combinations, but I got some ideas of how to quilt my own!
I made a hunters star baby quilt about 7 years ago, and for the life of me I can't remember how I quilted it!!!
