One Ball Chemo Hat – Free Knitting Pattern

by

If you’re looking for a quick, meaningful, and budget-friendly knitting project, this One Ball Chemo Hat Pattern is perfect. Designed with comfort in mind, it uses just a single ball of yarn and can be completed in an evening. The result is a soft, lightweight, and cozy beanie that’s ideal for anyone going through chemotherapy, hair loss, or simply wanting an easy beginner project.

Why This Hat Works So Well as a Chemo Cap

Chemo patients often have sensitive scalps, so choosing the right yarn is crucial. This pattern is written to be used with soft, non-irritating fibers—think cotton blends, bamboo yarn, or other gentle, breathable textures. The snug yet stretchy fit ensures it stays in place while still being comfortable enough to wear all day.

Unlike bulkier winter hats, this design is light enough for indoor wear, yet still offers warmth and coverage. It’s also a wonderful gift project—handmade chemo hats are always appreciated for their comfort and the love stitched into them.

Skills You’ll Need

This is a beginner-friendly knitting pattern. If you can knit and purl, you’ll be able to finish this hat with ease. It’s knitted in the round (or flat with seaming if you prefer), so it’s a great introduction to hat knitting for newer knitters.

Supplies

  • Yarn: 1 ball of soft yarn (cotton, bamboo, or acrylic blend recommended) 
  • Needles: Size US 8 (5mm) circulars or double-pointed needles (depending on your method) 
  • Notions: Stitch marker, tapestry needle for weaving in ends 

Customization Ideas

  • Add a stripe or two: Use a contrasting color to create bands around the hat. 
  • Decorative edge: Finish with a crochet border for a feminine touch. 
  • Accessorize: Knit a matching flower or bow to sew onto the side. 
  • Make it longer: Knit a slouchy version for extra coverage. 

Great for Charity Knitting

This pattern is ideal for knitters who want to make a difference. One ball makes one hat, so you can easily knit several to donate to cancer support groups, hospitals, or charity drives. It’s a meaningful way to use leftover stash yarn while helping others feel cared for.

Why You’ll Love This Pattern

  • Only requires one ball of yarn 
  • Quick knit – perfect for weekend projects 
  • Beginner friendly but satisfying for experienced knitters too 
  • Thoughtful gift for a loved one or donation project 
  • Can be easily personalized with color and style

Knit a Log Cabin Blanket with All Your Scraps

I guess I must have had this pattern on my mind, because I had chosen this log cabin blanket recipe to write about, promptly forgot about it and a couple of weeks later started knitting a log cabin blanket using all my pink yarn. 

It might stay pink if it makes it to baby blanket sized, or I might add in some pastel green and blue, too, to make a bigger blanket. We’ll see. I’m also holding several strands of yarn together to make a kind of bulky yarn, which means it’s deeply satisfying how much yarn is used even as the project is still relatively small. 

In Kristen Finlay’s version, DK weight yarn scraps (or fingering/sock yarn held double) are used to make a simple scrappy log cabin blanket that’s lighter weight than my version. Log cabin is a great technique for knitters of any skill level because it’s worked in garter stitch. The only not completely basic technique you need for log cabin knitting is picking up stitches. 

If you’ve never worked a log cabin knitting project before, this is a good introduction, and it is really nice to use all your yarn scraps in one big project you’ll use for years to come. 

If you use a lot of DK weight yarn you can keep building on it whenever you finish a project, or if you use more worsted weight you can do the same thing with it, it will just be a little bigger starting out than the pattern calls for. How big it gets is totally up to you. 

I have really been enjoying working on my log cabin project, and it’s my current sitting at my desk and need a break knit (do you have one of those or is it just me?).
