Hats

I love to wear hats but I don't knit them. I missed the knit-a-thon this weekend (darn grass seed/pollen) at Soft Horizons but did call to ask if I knit something at home if they would still accept it. They will so I am trying to find a good pattern for Caps for Kids. Suggestions?
I was looking at Halfdome. I love and have Debbie Bliss Cashmerino Aran on hand in some good colors. I also like Topi. I have some bright blue cotton that would look great knit up like this. The designer of Topi has great things on her site. I'll post pictures once I've started.
