I was too busy finishing off my minion army to post this last night!
Alasdair (4) has been asking for a minion hat for quite a while now so I made him one last week. Then when David (8) saw the finished product he said that he would like one too.
I didn't use a pattern for these as I have made enough hats in the past to know the basic shape. One day when I have a little more spare time (!) I will sit down and write up this one to share. If you can't wait until then though there are plenty different ones available online if you do a quick google search.
