What I'm About to Knit

I plan on knitting the Petunia Tote from Interweave Knits Spring 2007 edition. I can't decide if I'm going to buy another type of yarn or what. I need to figure this out. I want to get on it this week. I feel empty with nothing on the needles.

After or while I'm knitting the bag - depends how my attention span is - I want to follow this AMAZING tutorial on how to knit socks. The first one will be super-plain and then maybe I'll attack that ever-growing list on the right. Online I've seen some cool sock yarn that makes it look as though you did some crazy colourwork/intarsia as you go along simply because the yarn variates in colour in strategic ways.
