yarn in the mail

Receiving a package of yarn in the mail makes me so happy! :D The 12 balls of black sport weight yarn I bought off of eBay came today. I'm using them to crochet a Butterfly Wrap (pattern from StitchDiva). IF I can get this finished in November, I'll be able to wear it with my dress to the Nightwish and/or Evanescence concerts! The pattern itself isn't that difficult. The only thing I'm worried about is the tension. I don't want it to be too loose, or too tight, but at least since it's a wrap and will be tied....it probably won't matter very much.
