Seashell Crochet Baby Bonnet – Free Pattern

by Doroteja

Crochet baby bonnets are super easy to make, and you can wrap up the entire hat with just one skein of yarn. They are perfect last minute projects for baby showers and baby gifts. You usually don’t need any special knowledge of shaping, no decreases needed, only a few rounds of increases, which are nothing other than two or more stitches made into the same stitch from the row/round below. Easy peasy!

I won’t lie, I didn’t write this one from a scratch. I partially reused one of my old crochet patterns for it. Therefore the back of the bonnet is the same as with the Sunflower bonnet that I posted a while back and you can find here. The rest is a very simple crochet shell stitch pattern on a repeat.

Let’s talk about yarn. The pattern was initially designed with Paintbox Cotton Aran yarn. A great substitution for that yarn would be Drops Paris form Garn Studio, Epic from Yarn and Colors or Rico Creative Cotton Aran from Rico Designs. Those are actually my favorite cotton yarns, and I use them all the time. Most of my patterns are written with those, and I could talk for days about each. My favorite hook to go with any of those is 4.0 mm crochet hook. The stitches are nice and clear and the fabric soft and right enough stretchy.

You won’t need any special supplies for this project, just a pair of scissors and a tapestry needle to cut and hide the yarn tails between the stitches once you’re done crocheting.

If you decide the use this pattern, please share your finished bonnet with me on Instagram tagging me #crobypatterns. I would love to see it and give it a big <3.

  • YARN: Aran weight yarn – Yarn And Colors Epic – this is 100% cotton yarn, there is 50 g (1.75 oz) and 75 m ( 82 yds) of yarn in one skein. I will be using it in the color 47 or old pink. I love when the yarn color has a name. It’s so much easier to share what color I use.
  • CROCHET HOOK: 4.0 mm or G/6 crochet hook or a hook to obtain the gauge.
  • OTHER: two stitch markers, tapestry needle and scissors.

Stitches and Abbreviations

  • Sst/sts – stitch/stitches
  • ch – chain
  • ss – slip stitch
  • dc – double crochet
  • CL – cluster stitch [skip 2, work 2 dc, 1 ch, 2 dc into the same st, skip 2]
  • BPdc – back post double crochet
  • FPdc – front post double crochet


GAUGE:  Work 11 stitches and 8 rows in SC into BLO using a 6.5 mm crochet hook and Aran weight yarn to measure 10 x 10 cm (5 x 5 inches).

When you find a new crochet project that you would like to make, you usually want to start ASAP. We all do. But please take some time and check the gauge. It might save your project!

Checking the gauge is a crucial step in the process of making a new crochet/knit garment. It will help you achieve the right size of your finish item. Learn how to check your gauge here.

Crochet Baby Bonnet – Seashell

The pattern is written in two simple steps: bonnet and straps. We are going to start with the back of the bonnet and work our way up to the front.

  • Add this pattern to your Ravelry queue HERE.
  • PIN this pattern to your favorite crochet Pinterest boards for later HERE.
  • Follow me on Love Crochet and get updates when I post new patterns HERE.
  • Share your work with me on social media using #crobypatterns.


The first part of the bonnet is made in rounds. Each round is joined with a simple stitch, connecting the first and last stitch of the round together. This is also a part of the pattern where the number of stitches increases with each round, each round for ten additional stitches.

The fabric you will be making here should be in the shape of a bowl and not entiery flat as you would expect. After all, baby’s head is not flat at the back eather. Therefore we have to crochet it accordingly.

Work in rounds. Do not turn after each round. Join each round with a ss made into the first st of that round.

MR (magic ring).
Round 1: Work 10 dc into the magic ring. Pull the yarn tail and close the magic ring. Ss. = 10 sts.

Round 2: Ch 1. Work 2 dc into each if next 10. Ss. = 20 sts.

Round 3: Ch 1. Repeat {2 dc into the same, 1 dc into the next one} 10 times. Ss. = 30 sts.

Round 4: Ch 1. Repeat {2 dc into the same, 1 dc into each of next two} 10 times. Ss.= 40 sts.

Round 5: Ch 1. Repeat {2 dc into the same, 1 dc into each of next three} 10 times. Ss. = 50 sts.

From here on work in rows. Turn your work after each row.

Our first row will end up with one stitch less then round 5. In row 6 we are going to stop crocheting one stitch before the end of round 5 chain 1 to lift the row and turn our work. With skipping this one stitch in row 6 we get the perfect amount of stitches we need for our further stitch pattern and a nicer opening at the bottom of the bonnet.

Row 6: Work 1 dc into the same. Repeat {CL, 1 dc into the next} 8 times. Skip the last st of the row, turn your work and start with the next one. = 49 sts.

Row 7: Work 1 dc into the same. Repeat {CL, 1 BPdc into the next} 7 times. CL. Work 1 dc into the last one. = 49 sts.

Row 8: Work 1 dc into the same. Repeat {CL, 1 FPdc into the next} 7 times. CL. Work 1 dc into the last one. = 49 sts.

Repeat rows 7 and 8 two more times.

Cut the yarn and fasten off. Hide all the yarn tails between the stitches and the main part of the bonnet is not complete. Continue with the strap.


We are going to start on one end of the strap, then we are going to attach the strap to the bonnet and work our way up to the other end of the strap. 

After that, we are going to turn and create one additional row of stitches to make it stronger and comfortable to wear and tie in a bow.

Row 1: Ch 42 (46). Join with the lower part of the bonnet. Work sc sts across the lower part of the bonnet. 2 sc into every dc from the side and also 2 sc sts into the skipped st from row 6.

When you complete that ch 43 (47). Turn.

Row 2: Start in the 2nd ch from the hook. Work 1 ss into each of next 42 (46) chains, 1 sc into each of next 30 (38) sts. Work 1 ss into each of next 42 (46) chains. = 114 (130) sts.

Cut the yarn and fasten off.

Hide all the tails between the stitches and your adorable baby bonnet is now complete.

I bought the bonnet pattern and watched the video but my bonnet isn’t turning out right. Can you help me with this? Your bonnet has a “point” on top mine is flat.

Doroteja February 4, 2020 - 10:09

I am so sorry to hear that Ashley. It might be problem in the gauge or even in the yarn. Send me a message on Etsy and we will find the solution together. 🙂

Kara August 20, 2020 - 00:51

Lovely pattern. Eady to follow except I am not getting the sc instructions once the first strap is attached and then one is to sc across the back.

malin November 1, 2020 - 16:58

Doroteja March 17, 2021 - 14:44

Thank you for letting me know, Malin! 😊🙏

Mary Beth January 23, 2020 - 01:03

I have crocheted off and on for years. But never felt confident in my work. I started up again here at age 74 and saw the Baby Bonnet and decided to try it. It turned out so beautiful I couldn’t believe it. How perfect were your directions. Trying the booties next. Thank you so much for your clear and concise pattern on YouTube!

Carole August 19, 2020 - 20:49

Doroteja August 20, 2020 - 12:10

Hi Carole! You can find all the patterns here: 😊 Happy crocheting!

B dietrich September 23, 2020 - 17:48

Is there a pattern for matching seashell booties?

Doroteja September 24, 2020 - 11:31

Unfortunately, not at the moment, but it’s definitely an interesting idea for a future project. 😊

Deevy October 4, 2020 - 01:35

Hi! Just made 2 of these & they came out great. Thank you! Also bought a few more patterns off your Etsy 👍🏼

Doroteja October 20, 2020 - 12:54

Thank you very much, Deevy! 🥰

Francesca Jones February 25, 2021 - 18:15

Hi I wonder if you could help? I have crocheted your bonnet today and it’s beautiful, but its tiny 🙁 it fits my daughters doll but. I did a hat a few weeks ago from another pattern and that too came out so small. I just don’t know how. For this bonnet I used a 4 mm hook and the size yarn suggested. Any tips would be amazing. Thank you

Doroteja March 17, 2021 - 11:16

Hi! It’s hard to say, but I think your stitches might be a bit tighter than mine. Try a larger crochet hook and maybe a thiny bit thicker yarn. It might help. 😊
Good luck!

Bernike June 17, 2022 - 16:33

Heyyy, lovely pattern, thank you very much.

Just want to let you know that in row 6 the written pattern says: {CL, 1 DC in next}. and video it says to skip 2 before the 1 DC.
The video is correct i think, right?

Doroteja August 31, 2022 - 10:27

Hi Bernike, thanks for letting me know! I will check both instructions and correct the pattern accordingly. ☀️

Maria Elena Martinez October 18, 2022 - 17:44

I am not able to follow the pattern, after five row. Can you help me.?

Doroteja October 25, 2022 - 10:56

Hello Maria Elena, which part of the pattern do you need help with?
