Crochet Bucket Hats

To crochet this sweet Granny Square Bucket Hat, you'll need to know how to crochet 3 things:

1. A Classic Granny Square

2. A Flat Circle

3. Increases in rows for a ruffled brim.

In previous posts, I showed you how to crochet a Granny Square, and how to crochet a flat circle. If you're not sure how to do these, you can refer to these posts and come back here for the Granny Square Bucket Hat Pattern.

Interesting Note: Did you know that the technique used to crochet curly or ruffled surfaces is called hyperbolic crochet? When I discovered this was actually a mathematical term for "negative curvature", I was really intrigued! 

Think of the types of curvature you see in coral reefs or lettuce leaves. These organic shapes can be replicated in crochet by adding stitches at a constant rate to each row of crochet. The more frequently you add stitches, the curlier/more ruffled (and more negatively curved) your crochet project gets.  Isn't that awesome?! You can watch a video about hyperbolic crochet here.

Now let's experiment with hyperbolic crochet with the brim of our Granny Square Bucket Hat...

What You’ll Learn

Materials Needed

Some classic worsted weight yarn (4 colors of your choice). Any yarn would do really, just make sure it's not hairy or fuzzy and that they are all similar weight yarns.  I used Paintbox Yarns for this crochet bucket hat.

  1. Blush Pink (353) - Color A
  2. Raspberry Pink (343) - Color B

Crochet Bucket Hat Measurements (Gauge)

Bucket Hat Top

For the top of the hat (the flat circle), I've prepared a simple template that you could download and print (below). Find the size you are aiming for and place your crocheted circle on the paper to check sizing.

Crochet Bucket Hat Sides

- For this project I find it best to try on the hat for a comfortable fit. Depending on the size you're aiming for, you might only need to make 4 Granny Squares for a child, 5 for an older child and maybe 6 for an adult.

- For this bucket hat, I crocheted 3 rounds for each Granny Square. If you want to make this bucket hat for a baby, you might only want to crochet 2 rounds, use finer yarn or a smaller crochet hook.

- If you need an in-between size, you can crochet a round or two of sc (single crochets) around each Granny Square to make them slightly bigger. 

- Remember that the joining method using sc2tog will also create some more space between the Granny Squares, so once you have them all joined, check to see that you have the circumference size you are happy with.

Crochet Bucket Hat Brim

Bucket hat brims come in all widths and styles. For this project I chose to make a ruffled brim in 4 colors.  

  1. The first row is a dc (double crochet) in lime green.
  2. The second row is a dc increase in Raspberry Pink
  3. The third row is hdc (half double crochet) increase in Ballet Pink
  4. The fourth row is a sc (single crochet) increase in Blush Pink.

The ruffled effect is made by increasing in every other stitch.


- You can use any type of yarn as long as you have a corresponding crochet hook size (check yarn label for recommendations). Granny squares are great stash busters, so you could easily make this bucket hat with leftover yarn.

- For this bucket hat I used acrylic yarn. I find it more forgiving than cotton yarn and it's a little more stretchy which makes it easier for fitting.

- If you need more detailed instructions on how to work the required stitches, check out Annie’s Catalogue for visual step by step instructions with pictures.

- You can make the pattern larger or smaller by changing the type of yarn and/or hook size, adding a row or 2 of sc around each Granny Square or increasing/decreasing the number of squares.

- Numbers at the end of each row [in brackets] indicate the number of final stitches in that row/round. 

- Please note that I use US crochet terms.

There are several ways to crochet a classic Granny Square, but what I'll show you here is the simplest and most straight forward in my opinion. Here we go:

  • Start off by tying a slip knot with the Blush Pink yarn, then Ch 4. You could also try the Magic Circle for a tight & closed center if you wish.
  • Join to first stitch with slip stitch to form a circle.

Round 1: (Color A: Blush Pink)

  • Ch 3 (counts as first double crochet)
  • 2 dc into center of circle, ch 2, (3 dc into center of circle, ch 2) repeat brackets 2 more times 
  • Join with sl st to top of first ch 3 at beginning of this round. Leave a short tail, cut off your yarn. Pull through loop tightly to secure.

You should have 4 clusters of 3 dc at this point and 4 corners (the ch 2 after each cluster creates a corner).

Round 2: (Color B: Raspberry Pink)

  • With your Raspberry Pink yarn, make a slip knot. 
  • Put your hook though the ch1 space to the right of your Blush Pink yarn tail and hook on your Raspberry Pink slip knot from the back.
  • Optional: Try to hold your Blush Pink & Raspberry Pink yarn tails as you crochet over them with your Raspberry Pink working yarn now so you don't have to weave in these ends later.
  • Ch 3 (counts as first dc, 2 dc into same corner space, ch 2,  3 dc into same corner space, ch 1 (This is a corner cluster)
  •  * skip to next corner space (big hole) and work 3 dc, ch 2, 3 dc, ch 1.
  • Repeat from * 2 more times (one in each corner space) 
  • In final corner, join with sl st to top of ch 3 (remember that chain 3 counts as a dc stitch)
  • Leave a short tail, cut off your yarn. Pull through loop tightly to secure.

Round 3: (Color C: Ballet Pink)

  • With your Ballet Pink yarn, make a slip knot. 
  • Put your hook though the ch1 space to the right of your Raspberry Pink yarn tail and hook on your Ballet Pink slip knot from the back of your Granny Square.
  • Optional: Try to hold your 2 yarn tails as you crochet over them with your Ballet Pink working yarn now so you don't have to weave them in later.
  • Ch 3, 2 dc into same space, ch 1,
  • Skip to corner space (* in corner space work 3 dc, ch 2, 3 dc, ch 1
  • Skip to next ch 1 space and work 3 dc, ch 1)
  • Repeat from * to end of brackets 3 times 
  • Work final corner, 3 dc, ch 2, 3 dc, ch 1 and join with a sl st to top of ch 3. 
  • Leave a short tail, cut off your yarn. Pull through loop tightly to secure.
  • When you're done with your Granny Square, take a tapestry needle and weave in your ends for a clean finished look. If you've already crocheted over them as you worked your rounds, then just snip off the excess with your scissors and weave in your last tail only.
  • Once you're done with your first Granny Square, repeat the steps above to make 4 more (or depending on the size you're aiming for, reduce or increase the number of squares).

How To Join Granny Squares

For this project, I chose to join my Granny Squares using the dc2tog method (double crochet 2 together) using a contrasting color (lime green).. I feel it gives the hat a nice look and allows for some space between the Granny Squares. There's a video tutorial below, but if you prefer a written pattern, you may follow these directions:

  • Lay all your Granny Squares side by side in one row, right sides facing up.
  • Lay the first 2 Granny Squares right sides facing up and start working your first stitch in a corner space of one granny square.
  • Make a slip knot on your hook, insert hook into corner space, yo (yarn over), pick up a loop, yo, pull through 2 (you will have 2 loops remaining on your hook)
  • *(Yo, go into a corner space of the next granny square you're joining, yo, pull through 2, yo, pull through all 3 loops on your hook.
  • Back to first granny square, skip a stitch, yo, pick up a loop, yo, pull through 2
  • Over to the second Granny Square, skip a stitch, yo, pick up a loop, yo, pull though 2, yo, pull through all 3 loops on your hook)
  • repeat * brackets to the end of your granny square side.
  • *(Once you've reached the end of that side, ch2, dc into the corner space, skip a stitch, dc along every other stitch (7 dc))
  • At this point, join the 3rd Granny Square using the same method.
  • When you reach the end of that side, you will repeat the dcs as above * in brackets for the other side of the Granny Square.
  • You will be crocheting in the following way: 
Crochet Granny Square Bucket Hat Diagram
  • To move from one completed Granny Square to the next, sl st loosely across green border till you get to the next granny square corner
  • dc in next corner (counts as 1st dc), dc across skipping a st in between (7 dc per side)
  • join to next green corner with a sl st
  • sl st across green border till you get to the next granny square corner (8 sl sts)
  • dc in corner of next granny square (counts as 1st dc), skip a stitch & dc in every other stitch across (7 dc), sl st to first dc
  • You have now completed the circle of granny squares (head circumference)
  • For my 5 Granny Squares, I had 36 stitches at the circumference of the granny square circle

For a video tutorial of how to use this dc2tog joining method, have a look at this video below.

How To Crochet Hat Brim

You may choose to crochet a solid-colored brim or multi-colored as below.

  • Continue with Green, (2 dc in first st, 1 dc in next 2 sts), repeat brackets around. Leave a 4 inch tail, cut yarn and fasten off.
  • Change color to Ballet Pink, (2 hdc in first st, hdc in next), repeat brackets around. Leave a 4 inch tail, cut yarn and fasten off.
  • Change color to Blush Pink, sc in each st around, leave a 4 inch tail, cut yarn and fasten off.

How To Join Bucket Hat Top With Granny Square Sides

Now depending on the size you chose for your flat circle (top of hat) and the number and size of the granny squares (for the sides), you will most probably have a different number of stitches on the circle circumference that you'll want to attach to the granny square circumference.

Crochet Granny Square Bucket Hat Attaching Top

What I did was attach one stitch of the flat circle (top) to one stitch of the Granny Squares and secure those with a stitch marker or simply tie a knot with a snippet of yarn (contrasting color for better visibility).

I then folded both the top circle and granny square circumference circle in half and attached the opposite ends in the same way.

I continued to do this 2 more times by folding in half and attaching pieces of yarn to the edges of these folds. 

That way, I could more or less hold a quarter of the circle in my hand at a time and attach it to the corresponding granny square without losing or gaining too many stitches.

I proceeded to whip stitch the two parts together (top & side) with a darning needle all the way around using the Lime Green yarn. 

After cutting off the yarn and weaving in the end, I removed the snippets of yarn I used as references.

How many granny squares does it take to make a bucket hat?

The number of granny squared required for a hat may be different depending on:

  • the size of your hat (baby, child or adult)
  • the size of your Granny Squares (number of rounds, yarn & hook size)
  • the placement of your Granny Squares on your hat.

There are lots of ways you can crochet a bucket hat using granny squares. Some patterns call for 5 granny squares and include one granny square for the top of the hat, some use more granny squares for the brim, or smaller flower/daisy squares all around, but in this pattern above, I use 5 Granny Squares for the sides of the hat, a flat circle for the top, and rows of increases for the brim (either straight or ruffled/wavy).

How do you crochet a magic circle?

Starting off your hat with a magic circle is always a good idea. The magic circle is similar to a slip knot, except you don't pull it closed. You hold the open slip knot with your fingers and continue to crochet the required number of stitches into the circle. Once you've completed your stitches, pull the tail end of your 'slip knot' and pull your magic circle tightly closed.
