My nickname for this fun hat is “The Free Fudge Beanie” and there are several good reasons why: You have the FREEDOM to choose whatever size you want using whatever yarn and hook you want AND you can easily correct any mistakes you make with a simple FUDGE fix here and there! (Fudge is term for tweaking or modifying!) So… FREE FUDGE!
The Bead Stitch is traditionally done with a double crochet post but I modified it by using a half double crochet. This makes the stitch appear fuller with less chance of the stitch’s “feet” peeping out below the wrap.

I’m having Trouble downloading your pattern how do I do it
Well, that depends on the software you’re using to view it. When you click on the link, it loads the pattern in a .pdf format in your browser and you download it from there. Just Google “how to download a .pdf file in ________” where the blank is your browser.
What a cute baby hat. Thanks for sharing. I Hope to make some soon.
