2. The pattern says "block over a dinner plate or balloon". I've never done this before but it works remarkably well. It costs just a few pence for a balloon, plus I've sealed it with a food sealer here so I can re-use it!
The top of the hat is a little more puckered than it looks on the pattern, this could be because when I switched to dpns for the final decreases, I went down a size thinking this would be ok.
I'll post "start-finish" pictures when this has dried and I can model it.
