I made these two hats using Andean Treasure. I used this pattern www.vintageknits.com/jcrew.html
for the smaller one but I goofed when I measured it but it was for my 7 yo son and he likes it so it doesn't really matter. The larger one is for my FIL and I used the same pattern plus a hat calulator that I can't find right now. Anyway more FOs to come.
