Working on Stripes

The first project I ever attempted was a hat from a book I got in a craft store.  This was a big mistake, really.  It was just not made for learning.  I finished it but not before I thought knitting was too hard for me.  It was an ugly hat that was too small for me.  The second project I tried was a garter stitch scarf that was multi-color yarn in one yarn color and it went a little bit.

Currently, I'm working on a red and black scarf.  This is my first attempt at stripes.  In the pictures, you can see where it seems like it gets bigger and smaller in stitch tension.  Oops.
