I used Lion Brand Jiffy yarn and perused the Lion Brand site to find an appropriate pattern...found this one for Jiffy yarn! It is snug on him, so I hope it fits all winter, but the yarn seems to have a lot of give. Oh the pattern is for the Helmet Hat on Lion Brand's site, and I used size 11 straight needles for it. It only took about an hour, start to finish.
Ok, we're ready for snow now! LOL!
I'm working on a commissioned pair of longies right now...well, sort of. I'm doing a practice pair first for Luci so I can see what I'm doing before I try one for someone else! But I think it's going to be super cute!
