Cozy Chemo Hat

I wanted to share this pattern for a chemo hat. It has a nice flared brim, more “cloche-y” than brimmy, really, but a very cute hat and a very quick knit. The first photo is done in Cascade 220 superwash, the second photo is done in Malabrigo Kettle-dyed Worsted. 


You are welcome to knit this pattern – after all, it’s a freebie, however, please take the time to knit a second hat for someone you love, or know who may need it. Please don’t knit this pattern for resale – bad karma will track you down and crush your goolies!

(so there!)

    hey Margie-
    A kfb stands for knit through the front and back of a stitch. (another way of making a stitch) To do this, you put your right hand needle in as if to knit, yo, knit, but instead of taking the st off the left hand needle, you put the right hand needle back into the back loop of the stitch you’ve just “knitted”, then you completely knit that second “stitch” so you end up with 2 sts where there was one. Sounds complicated and wordy, but try it, it’s very simple once you actually do it!

    You put your first needle in, you put your second needle out, you do a yarn over and you shake it all about, you do the Yarny Hokey and you turn your hat around, and that’s what it’s all about!

    I’m very confused. Does this hat require seaming as I see no where in the instructions that says to either join and knit in the round or seam once it’s finished.

    I’ve just finished the first bind off.

    Hi, I just wanted to let you know that I made one of these for my local cancer center – and the style was a big hit! I’m currently working on my second one, and I’m going to make a few more for them after that. Thanks for posting this pattern, I think it’s really pretty, and I think a lot of chemo hats tend to look like ski hats and this one is much more feminine and flattering. Thanks again!

    Thanks Knitbrit for the beautiful pattern! You suggested Cascade 220 – about how many yards does the hat require? In other words, does one skein make one hat or will I have some left over? I plan on making a couple for one of my faculty members…
