Thanks, everyone. Yes, the batik one is the keeper. It's on a bed now... The one with the wavy lines was supposed to be a donation quilt, but I love how it turned out! It will have to stay around for a while so I can look at it! The blocks were made by the various swappers of the Boomerang swap... I only made two or three of them, myself.
I agree about the wavy lines. As long as you keep the lines a consistent width, you create good texture. It can be a hot mess and still look good, overall.
