Well, using Red Heart Super Saver (one of the orange yarns; look for the one that looks like it's safety vest orange), I made it for him!
Well, before he came to get it, my daughter decided that SHE needed it. So, I worked away on attempting to create a toddler version.... As soon as I get her to hold still long enough, I will post a picture of HER (and I'll snag the hat at some point to write down the pattern I used on hers....)
Enjoy your hat, J!
I said I'd post little one's hat, so, here it is!
