Sometimes? Sometimes... you need help

So, I finished the garden path socks! Whoo hoo! There is, however, a slight problem. Sock number two isn't nearly as comfortable as number one. It's a little too small, especially on the cast off edge. I may end up redoing it after Christmas. Who knew that switching from dpns to two circulars would affect gauge so much? I know I didn't... I guess I should've known it was affected though. The whole time I was knitting them I was complaining that even though there were the same number of stitches, the striping pattern was different. I guess I'm not that bright lol.

See how in the left sock as you look at it the stripes are so much bigger, but other than size, all the stripes are exactly the same? That is so irritating... Anyway, After I finished both socks, I had a ton of yarn leftover.

Any ideas as to what I should do with it?

Anyway, thanks for stopping by! I'm off to work some more on my story/novel thing. :)
