You can always use hats, especially now in the cold winter, but also when spring comes around again.
For the following hat patterns, you can use any yarn; the pattern will just turn out finer or chunkier accordingly. Since the hats are started from the cuff, they can be easily adjusted to any head circumference, so you can crochet hats for the whole family.
In addition, all patterns include lots of pictures and detailed explanations, so ambitious beginners can follow them well too.
