Here's an old book that has stayed in print. Each glove, mitten, hat or sock pattern is contributed by a different knitter. The patterns are not on the cutting edge style-wise, rather more in the classic, practical category. These two hat patterns are among my favorites & I've made them repeatedly. Especially the Birds & Bees cap is an all-time favorite which I've made four times in different color combinations.
