Second Sweater, fini

I've pretty much completed my second sweater, Rusted Root. I haven't taken pictures yet but will soon. I pretty much followed the pattern, but ran into a few mistakes. I had to start over three times. BUT! My third time I started on March 29th and finished on April 13th, so I think that's PRETTY DARN GOOD. Two weeks to finish a sweater? Granted it's short-sleeved, but whatever! Two weeks to finish a sweater!

I LOVE LOVE LOVE the way the yarn knit up (cascade sierra) And I have almost 2 whole skeins left. I bought four because the pattern called for 3 of another yarn that had 215 yds and the cascade only had 191, so to be on the absolute safe side, I got four skeins. And I've barely used the 3rd skein. I basically did the bottom ribbing (about 15 rows), the ribbing along the sleeve (4 rows) and the ribbing along the neckline (4 rows). Maybe I have about 2/3 of the skein left. But that still leaves me with almost 300 yds left! What the heck am I going to make with about 300 yds maybe of worsted weight cotton yarn?
