A while back I proclaimed that I made myself the perfect slouchy hat. I still stand by that =) but I made some tweaks that, in my opinion, make it even more...perfect! I kept the same basic shape but used an open stitch (dc + ch 1 in the place of one dc). I first tried a super slouchy version using Bernat Softee Chunky yarn.
I've used a soft, thick yarn for a warmer winter hat
but I think my favorite version is made with Caron Simply Soft and a K hook.
It's very soft and lightweight, a great addition to any wardrobe.
