A Basic Level Knitting Pattern

If you are learning how to knit, baby knitting patterns are great to start with before you move on to more complicated patterns that include cables and other advanced techniques. 

When you knit a baby hat you will be able to practice basic knitting stitches and learn to shape the top of the hat with simple decreases.

The hat is knit with straight needles and is seamed to finish.

This means that it is not knit in the round with circular needles.

The Yarn I Used To Knit The Baby Hat

I used Rico Creative Cotton Aran (50g/85m/93yds) for the hat in the color Smokey blue.

The cotton does on occasion split when you knit, like most cotton yarns but you can fix it and make it look neat with a little patience.

This is a medium-weight yarn 04.

You can substitute with most cotton including most DK yarn that is compatible with size 4.5mm (US 7) knitting needles.

Yarn Substitutes

  • Jarbo Garn – Reko Bomull
  • Drops Design – Drops Loves You 8
  • Scheepjes – Cahlista
  • Paintbox Yarns – Cotton Aran
  • King Cole – Big Value Recycled Cotton Aran
  • Cascade Yarns – Nifty Cotton

How To Knit A Baby Hat

  1. The Turned Up Brim

    Cast on 54 (61/69) sts.
    Row 1 (RS): P1, K2 – rep to the end of the row.
    Row 2 (WS): P2, K1 – rep to the end of the row.
    Rep rows 1 and 2 until the piece measures 2″ (2.5″/3″) from the cast-on edge.baby hat tutorial step 1

  2. The Main Body Of The Hat

    Row 1 (RS): K1, P2 – rep to the end of the row.
    Row 2 (WS): K2, P1 – rep to the end of the row.
    Rep rows 1 and 2 until you have worked 7″ (8″/9″) from the cast-on edge ending with a WS row.baby hat tutorial step 2

  3. Decrease

    Row 1: K1, P2tog – rep to the end of the row.
    Row 2: K1, P1 – rep to the end of the row.
    Row 3: K2tog – rep to the end of the row.
    Row 4: Purl – rep to the end of the row.
    Row 5: K2tog – rep to the end of the row.
    Row 6: Purl – rep to the end of the row.

    Cut yarn leaving a tail of around 15 inches.
    Thread through the rem sts and pull up tight.baby hat tutorial step 3

  4. Making Up

    The last step is seaming the two edges of the baby hat together.
    I used a seaming technique called the mattress stitch.
    This allows you to create an invisible seam in your knitting so you don’t see where the edges meet.

    To do this you:
    Place the edges together – line them up.
    Start at the top of the hat, with the right sides facing you.
    Thread your needle and secure the top of the hat first with a stitch.
    Then start to push the needle through the first stitch on one side of the fabric edge.
    Then move over to the other side and push your needle through the first stitch.
    Pull them together and continue to seam picking up an edge stitch on one side and again on the other as you go.
    You can pick up stitches on every one bar or two bars on the edges – this is up to you. I generally pick up every 2 bars.
    Just be careful that what you do to one side of the knitting should also be done on the other side to keep them even.baby hat tutorial step 4

  5. Finishing

    When you come to the brim of the hat, you need to turn this over – so the right sides are facing you to seam.
    This is so you get an invisible seam on the right sides of the knitted fabric.
    When you have finished seaming, secure your yarn on the wrong side and weave in any loose ends.

  1. Thanks for sharing your patterns. I’m a first time granny and would love baby knitting patterns. Would really appreciate it.

  2. Thank you for the pattern! After a decrease row, do you start with knitting or purling for the 3 in between rows??

    1. Hello Zaynab,
      If the decrease row you have just worked is on the right side – meaning it was a knit row, then the next row would be a purl row, because you are working in stockinette stitch.
      I hope that helps!

    1. Hello Lisa,
      Thanks so much for your kind words, I’m so happy you enjoyed the pattern.
      Happy knitting!

    1. Hello Shira,
      The measurements are given in inches – for example, Rep rows 1 and 2 until the piece measures 2″ (2.5″/3″) from the cast-on edge.
      This would be 2 inches (2.5 inches/3 inches)
      I hope that helps!

  3. I think this might be a dumb question lol, but are you using circular knitting needles? And if you are, can this pattern be knit straight as well? Thanks!

  4. Is the sizing for the above instructions for a size 0-3 month? If so how many additional stitches are needed to make a 3-6 month size?

    1. Hello Crissy,
      This pattern is to fit baby sizes 0-3 months / 3-6 months / 6-9 months.
      The first set of numbers applies to the small size, the second set to the medium size, and the third to the large size.
      I hope that helps,

      1. Thank you! Since the 3-6 month hat is 61 stitches, an odd number, what do you do with the last/leftover stitch on Row 3 where it is knit 2 together to the end of the row?

        1. Hello Crissy,
          If you have one stitch left on that row, you can K1 at the end of the row.
          I hope that helps!

  5. Hi there! Thank you for this wonderful pattern. I’m using it to knit my first hat. Question: when you say to “end on a WS row” for the main body of the hat before beginning the decrease, does that mean you should complete a WS wrong and then begin decrease, OR complete a RS row and then begin decrease?? Thank you!!

    1. Hello Annie,
      This means the last row you worked was a (WS) – wrong side row, so the next row you will work for the decreases will be an (RS) – right side row.
      I hope that helps!

    2. Thank you so much for answering my question! I have another one 🙂
      Can you please elaborate on what to do after finishing the 6th row of purl in the decrease section? The instructions are “Thread through the rem sts and pull up tight.” but I’m not really sure what to do – any help would be greatly appreciated!!

      1. Hello Annie,
        You need to cut the length of the working yarn after that last row, thread a yarn needle/darning needle, and then thread that through the remaining stitches.
        Then you pull them closed tightly and start to seam the hat to finish it off.
        I hope that helps!
