Knitting is funny that way.

I’ve finally started my Jayne Cobb hat but I seem to be having some trouble.  I can’t seem to get gauge for some reason.  I bought the right yarn and the right needle size, but I’m getting 4 stitches per inch instead of 3.  So I doubled the yarn, but I’m still not getting it!  I swear, sometimes knitting defies the laws of physics.  I’m tempted to just keep going and see how big this thing turns out.
