Underway

I cast on the hat yesterday morning.  I have mixed feelings.  I am totally confident in my gauge.  I knit a damn fine mitt gauge swatch and measured very carefully.  But I still feel uncertain.  Sometimes I think it looks too big, other times I’m convinced it’s way too small.  I think it’s because I don’t know what ‘proper hat’ looks like laying there on the needles.  By this point, I am deeply familiar with what ‘proper sock’ looks like.  I can tell within 2 or 3 rounds if it’s going to be too big or too small.  Not so with the hat.  This is my first hat so I have no idea what it should look like at this stage in the proceedings.  Also, I don’t even wear hats, so I can’t even compare it to ‘reasonable sized commercial hat’ in my head.  On a related note, how the heck does one block a hat?  I’m fresh out of extra heads.  The current plan features a balloon and some rubber bands, but that may prove to be untenable.
