An Easy Knit Beanie

The hat pattern is easy to make, with advanced beginner knitters in mind.

Using knit and purl stitches, you will create 2×2 ribbing, knit in the round.

This knitted hat would take you around an hour or two to make (depending on how fast you knit!) and will be a cozy addition to the colder weather.

The Mariner’s Hat Design Inspiration

The style of this hat was inspired by a traditional British seaman’s cap.

Also known as a ribbed watchman’s hat, the design is made so that the hat has a snug fit and the brim turns up to keep the ears warm.

Great to make and gift, this hat is super easy to knit and will be well received by loved ones, friends, and charities.

The Yarn I Used…

I made the stretchy hat using Classic Alize Lanagold yarn in dark grey and knit on size 5.5 mm (US 9) 16″ circular needles.

The yarn I used is a medium-weight yarn (04), so you can substitute this with any worsted, Aran, or 10-ply yarn.

This was knit up quite quickly and used only one skein of yarn.

  1. I would like to knit this but a little nervous because it doesn’t require double points. When decreasing do you really keep it on the circular needles with no problem?

    Reply

    1. Hello, yes, it was fine when I decreased on the circulars, I didn’t have any issues at all. I mean you could change to DPN’s when you get to that stage if you wish. Thank you for visiting and taking a look around 🙂 Happy Knitting!

  2. So excited to knit this for my brother-in-law, but I only have US 8 sized needles. How many should I cast on to get the right size? I am using worsted weight yarn as well.

    Thank you!

    1. Hello, if you cast on 84 that should still work out ok – to go down a size to the US 8 needles. Thank you for visiting and taking a look around 🙂 Happy Knitting!

    1. Hello Brooke, If you are going to use a medium 4 weight yarn – you would be better off using 4.5mm – 5.5mm (US 7 to 9) needles. The hat was knit using medium yarn and size 5.5mm (US 9) needles. If you want to use 8mm (US 11) needles – you will need a Bulky (05) weight yarn. The pattern would need to be adjusted for that, as there would be too many stitches cast on – making the hat really huge! Thanks for visiting! 🙂

  5. Hi, I’m following this pattern and the hat seems to have a very small diameter. I’m about 8 rows in and was wondering if this is normal/Will it stretch or should I start over and cast on more stitches?

    Reply

    1. Hello, are you using the recommended needle size and yarn weight? If yes then it should be fine, it stretches because it is knit in ribbing. It has a comfortable fit – the ribbing allows for that. I hope that helps! 🙂

  6. If I wanted to make it a larger diameter (boyfriend has a big head and long thick hair) how would i adjust to cast on? Just make sure it’s an even number? I’m a new knitter 😊

    Reply

    1. Hello Anastasia, yes, if you adjust the number of sts you cast on for the hat, keep an even number and you should be fine. Then you just need to adjust the decreases for the crown also. 🙂

  7. Hi! I want to knit a few of these for our local cancer center. If I have bulky yarn and size 11 needles, how many stitches would I need to cast on? I think if I have that starting point I can adapt the pattern myself….

  8. Hi Louise! I am new at knitting and just completed matching beanies for my daughter and grandson using your mariner beanie pattern. I’m getting ready to start matching beanies for my daughter and SIL but she’s picked a super bulky 6 yarn. Can you offer me some guidance? The yarn calls for 13 (9mm)…can you help me adjust? I love using the no.10, 16 in circular, but thinking that’s not going to work.
    I looked through MANY beanie patterns before finding yours and was so glad I did! Thank you in advance!

    1. Hello Debbie,
      I’m so happy you enjoyed the pattern!
      You can search all of my hat patterns in the main menu – women’s hats and headbands and in men’s patterns.
      There are quite a few choices that use super bulky yarn.
      Happy knitting!
