If you’ve been crocheting with me for several years, or if you found this site through one of my popular crochet chemo cap patterns, you’ve probably heard about the Crochet Cancer Hat Challenge I participate in almost every year.
Most, if not all of those crochet chemo hats are available online for free year round, but every year a group of designers get together and offer PDF copies for free in exchange for pledges to make and donate hats to cancer centers or people you know personally who are in chemo or other health treatments.
This year has been tough for our family- with a really wild change of plans that required 2 military moves, an extended (3.5 months) stay in a hotel in between, a very tumultuous search for housing, and a switch from public schooling to home schooling.
I’ve barely crocheted at ALL due to the upheaval- but I couldn’t bear to skip this challenge. It’s too important to me, and to so many of you, who are dealing with health issues, or have family who are.
Both our grandfathers have had hospital stays this year, so I knew I wanted to dedicate my hat to a men’s health issue- so I’ve made my chemo cap in light blue, for prostate cancer.
This hat is far from perfect- I’ve only written it for one size, though I’ve given some general instructions on how you could try to resize it, and as always, I’m here to crochet along with you!

Looking for an alternate finish method?
Lemon peel stitch texture is pretty tricky to decrease and keep the pattern. If you’re not looking for a cap style, you could also just make the sides of the hat a bit longer, about 26 rounds for an adult size, and simply cinch them shut with a long yarn tail.
