"Winds of the Seasons"

This is my entry for our quilt guild's show challenge (only doing it since it can be entered as "non-judged"...LOL) The challenge is to take pre-printed squares/pictures of some type, cut them apart and make them your own. Back around Christmas, my MIL had taken me fabric shopping and these seasonal squares were one of the purchases we made. I took the changing seasons blocks, chose one color from each season and made little pinwheel blocks to separate them and carry over the feeling of the changing seasons, hence the quilt's name. As you can see it's not quite done yet. I can't decide if it needs another border--perhaps out of the blue coordinating fabric I used in the pieced sashing or maybe a pieced border using the different colors? Then I need to quilt it (likely by hand since my machine has been misbehaving and won't feed fabric right), and then bind it off in the blue. If anyone has border suggestions (or if you think it doesn't need one), please leave me a comment with your suggestion!
