PATTERN NOTES
This hat is worked top down, first with half double crochet in joined, unturned rounds, then in the Almond Ridges pattern in joined, turned rounds. When working the Almond Ridges pattern, you will work in the back loop only.

This pattern uses U.S. crochet terminology.

If you desire a longer hat, work rounds of half double crochet evenly before moving on to the Hat Body. Note that this may require more yarn than what is suggested.
