Halloween is nigh upon us

I've narrowed my costume choices to three:

Where's Waldo

Pepper Ann:

Or Spinelli from Recess:

I'm leaning towards Waldo because I think a) he's the most recognizable character, b) the costume would be pretty easy to reproduce, and c) because I found a pattern to knit a Where's Waldo hat.  But at this point in the game, I'm not sure.

Also, I'll hopefully be carving pumpkins tomorrow.  Think this pattern looks good?
