One Stripe Turtleneck Shrug

Well it's a good thing cooler weather is still around here in Atlanta, because I just finished my Turtleneck Shrug! I was worried I'd have to wait until next year to wear it. Woo hoo! I used Andean Silk from KnitPicks.com and knit with a size 4 needle. The sleeves are about 2.5 inches shorter than the pattern calls for. Still - they're pretty long on me. On one sleeve, I knit a lighter green stripe with some leftover yarn from my stash.

This is a very comfortable shrug, but I am considering shrinking it a bit. I've knit 2 others from another pattern that fit really snuggly and stayed in place. This one, after a few minutes of moving around (I'm right handed), shifts off my right shoulder. I think if it were tighter, it wouldn't move around as much. Any opinions? Advice?

Thanks for inspiring me everyone,
