....and the winner is...

Jeanne from A Bluestocking Knits! I'll be sending off a copy of Mindful Knitting later on today. Thanks to everone for voting and sharing opinions - it all really helped. Last night I finally decided on which button to use after trying on the almost completed sweater and holding up buttons against the front. I was thinking of using the last metallic buttons, but on the actual sweater they get lost and are a little too small. The leaf buttons are perfect, and those are what I'll use. Now to figure out buttonhole spacing!
