Seaside Sun Hat Crochet Pattern Design

When imagining a design for this hat, I knew I wanted it to be easy and beginner friendly, with simple details. I also really wanted it to be functional, a bit stiff so it held some shape but also slightly floppy for a beachy look. I gauge swatched with so many hook sizes to find one that created just the right ‘stiff but not too stiff’ fabric.

The little cable stitch details on this hat are super easy to work. When I started crocheting, I loved stitches that were easy to make but looked complicated! These stitches do just that!

Yarn and Materials

The yarn that I chose for this hat and shawl set is 24/7 Cotton from Lion Brand Yarn. I love this yarn because it is mercerized for added strength and nearly impossible to split between your hook. If you plan on using this yarn for your Seaside Sun Hat, you might want to check out the kit with Lion Brand! The kit contains the yarn needed for this project and a free PDF of the pattern.

Depending on the hook size and stitch you use, this yarn can give you dramatically different looks so I knew it was perfect for this hat/shawl set.

24/7 Cotton is definitely not soft, but not ‘rough’ either. I think its the perfect material to make summer items. If you are looking for a softer yarn or something with a different look, I have some great options listed below!

Yarn Substitutions

  • Cotton Ease by Lion Brand: This yarn is back for a limited time but I’m hoping it sticks around for a while! Its a cotton acrylic blend and it more on the heavy worsted side so definitely gauge swatch with this!
  • Just Hemp by Lion Brand: Another yarn on the heavier side, Just Hemp would give such a cool, natural vibe to this hat. This yarn is a little tough to work with though so just keep that in mind!
  • Re-Up by Lion Brand: Re-up is almost like a dishcloth cotton yarn, definitely easy care and easy to work with!
  • Rewind by Lion Brand: This is the yarn used in my Cove Tote. I held this yarn double in that pattern but holding it single would give a really nice basket type look as well. It’s nice and soft too so won’t bother your hands at all as you work!
  • Dishie from KnitPicks: Another dishcloth type yarn. Easy care, easy to work with, straightforward and durable!
  • Billow by KnitPicks: This yarn is labeled as bulky but I find that KnitPicks yarn is always a bit thinner than labeled. Personally, I think this is more of a heavy worsted!
  • Raffia Yarn: I think this yarn would make a super cool straw-type hat. I’ve used this exact raffia yarn and its almost like a papery grass material. I will note, raffia is a bit harder to work with than regular yarn but is definitely worth the extra effort if you want a straw look!

As always, be sure to gauge swatch, especially when substituting yarn. Small differences in gauge can lead to large changes in the size of the finished item! Swatching with this hat is especially important to get the right stiffness level!

This hat will be constructed in the round from the top, down. You will first work the top of the hat, shape the dome, and then finally work the brim.

  • Unless otherwise noted, hat will be worked in a spiral without joining rounds.
  • If there is a chain st/sts at the beg of a round, it will count as the first st of that round.
  • If a round is states [SC, inc] around. This means you will rep SC, inc, SC, inc, SC, inc … until the round is completed.
  • At the end of each round, place a marker in the st you have just worked. This will denote the final st of each round. When you come to this st on the next rd, remove M and replace in final st of round.

  1. Hi Kaitlin,
    I love this hat pattern! I’m done with the dome and starting in the brim. How many repeats of SC15, inc (row 37) should I do?

    Thanks so much.

    1. Hi! So glad you are enjoying the pattern!

      For row 37, you should work (SC15, inc) five times. In addition, you are working (SC14, inc) at the beginning of this row, so you will be increasing 6 times total to get you to 102 stitches!

      Hope that helps 🙂
