While we camped this summer, I worked on these knitted hats for all of Anne and Jack's little friends (7 boy hats and 6 girl hats).
Using the Knifty Knitter loom made these super fun and fast. No counting stitches or patterns. You can literally make a small hat in one movie sitting. You can get these looms at most craft stores. They are actually great for young hands too. My friend's 5-year-old made some hats for her friends.
For the girl hats, I added a fabric flower. (See here for flower-making instructions).
