My First Sweater(Jumper)!

I cast on my first sweater last night.  This is my first time working from a chart that isn't just colours but is different stitches.  It's 107 stitches across and this is just the back.  I have a feeling I will be working on this for quite a while but I've already learned to knit and purl through the back loop so it's a good day.  Can't wait to see what it does to the pattern!  The sweater is all vintage inspired and I'm making it in a lovely brown.  Brown wool with cables, this is gonna be a very warm sweater!
