This pattern is deceptively simple – it’s simply a length of garter stitch worked flat with the corners folded in and stitched together! With careful attention to the cast-on and cast-off techniques (to ensure they match) and with clever use of garter stitch seaming techniques, this Hat can be made in any gauge, in any yarn. And it’s absolutely perfect for beginners.



24 sts x 48 rows to 4in/10cm on 3mm needles over Garter St.



To fit sizes: 16 [18, 21, 23] in/ 40.75 [45.75, 53.25, 58.5] cm

K: knit
st(s): stitch(es)

How To

With main yarn and using Crochet Provisional cast-on method as a permanent cast-on, cast on 42 [48, 54, 60] sts. Try to leave a tail of around 9 [10, 11, 12] in/ 23 [25.5, 28, 30.5] cm



Row 1: Knit all sts

Row 2: Knit all sts

These two rows create garter stitch. Repeat these two rows until work measures approximately 16 [18, 20, 22] in/ 40.75 [45.75, 50.75, 56] cm from the cast on edge, with the garter stitch relaxed.

Cast-off loosely using the regular cast-off method. Using a larger needle can help stop the cast-off becoming too tight. Leave a tail of around 9 [10, 11, 12] in/ 23 [25.5, 28, 30.5] cm



Fold work in half length-ways.
Using the yarn tails, and using the mattress stitch method for garter stitch, close each side seam. You may wish to either duplicate stitch or use the ends of the yarn to otherwise tidy up the bottom edge at the seam points and keep the chain continuous.

If your yarn tails both end up on the same side, use a scrap of remaining yarn to close the seam.

Turn work inside out and bring together the top corners and secure them with a few stitches. Turn work back to the right sides.

Weave in all ends. A gentle wash and blocking is required to help the stitches settle.


Custom any gauge version

Should you wish to use a different yarn at a different gauge, you’ll need to know your head measurement and how many stitches across 4in/10cm your yarn gives you, which in turn will tell you how many stitches per inch or centimeter.

Armed with your head size, you’ll want to subtract between 2in/5cm and 3in/7.5cm or about 12% to 15% – this allows for negative ease (how much smaller the finished size compared to the to fit size) and it’s negative ease that helps keep the Hat on your head.

Now that you have the finished size of your Hat, divide that by 2 – this will tell us how wide the strip of garter stitch needs to be.

Then multiply this by the number of stitches per inch or centimeter – this tells us how many stitches to cast on. Round that number to the nearest whole stitch and grab your needles!


Your head size is 21in, and so an ideal finished size is 18in. That means our strip of garter stitch needs to be 9in wide.

Your yarn is a worsted weight yarn that gives 5sts per inch. We then multiply 9 (width in inches) by 5 (no. of sts per inch) to give us the cast-on number.

Simply knit the length of garter stitch until it’s double the Hat length and voila! Finish as above.
