That’s a fantastic idea! Using scrap yarn for a multicolor crochet bucket hat is not only eco-friendly but also results in a wonderfully unique and vibrant accessory. It’s a perfect project for a beginner looking to expand their skills, especially with color changes.

How to Crochet a Multicolor Bucket Hat from Scrap Yarn: A Detailed Guide
This tutorial will show you how to create a classic bucket hat, working from the top down, with frequent color changes using your scrap yarn stash.
1. Essential Materials You’ll Need
- Scrap Yarn: This is the star of the show! Gather all your worsted weight (Aran / Medium / Category 4) cotton yarn scraps.
- Cotton is highly recommended for bucket hats, especially in a warm climate like Phnom Penh, as it’s breathable, durable, and holds its shape well.
- Aim for similar yarn weights/fibers: While you can mix yarn types, for a smoother finish, try to stick to worsted weight cotton or cotton blends. Different weights can lead to an uneven fabric.
- Quantity: You’ll need approximately 100-150g total for an adult-sized hat. This means you can use many small balls of yarn!
- Crochet Hook: A 4.0mm (US G/6) or 4.5mm (US 7) hook. The key is to achieve a firm and dense fabric so the hat stands up and holds its shape. If your stitches are naturally loose, go down a hook size.
- Scissors: For cutting yarn.
- Yarn Needle (Tapestry Needle): Absolutely essential for weaving in all those loose ends from color changes.
- Stitch Marker (Highly Recommended!): To mark the beginning of each round, as you’ll be working in continuous spirals. This is especially helpful when changing colors.

2. Basic Crochet Stitches You’ll Use
This pattern primarily uses fundamental crochet stitches:
- Magic Ring (MR) / Adjustable Ring: (Highly Recommended!) Creates a tight, hole-free center for the top of your hat. Alternatively, you can
ch 4, then sl st to join
into the first chain to form a ring. - Chain (ch): Used for starting.
- Slip Stitch (sl st): For joining rounds (though we’ll focus on a continuous spiral for less visible joins) or for neatening.
- Single Crochet (sc): Creates a very dense, sturdy fabric, perfect for a hat. This will be your primary stitch.
- Working in Rounds (Continuous/Spiral): You’ll build the hat from the top down in a continuous spiral, which creates a seamless look without a visible seam line. This is great for multicolor projects as it blends color changes more smoothly.
- Fasten Off: To securely end your work.
- Weaving in Ends: Hiding yarn tails for a neat and professional finish – a very important step for multicolor projects!

Understanding Color Changes in a Spiral
Since we’re working in a continuous spiral (no slip stitch to join at the end of each round), color changes will create a slight “jog” where the new color begins. This is perfectly normal and part of the charm of a multicolor, scrap yarn project!
How to Change Colors (Seamless Transition Method):
- Work your last stitch of the current color up to the last yarn over. You should have two loops on your hook.
- Drop the old color. Pick up your new color.
- Yarn over with the new color and pull through both loops on your hook to complete the stitch.
- Continue crocheting with the new color.
- Leave about a 4-6 inch tail of both the old and new colors to weave in later.
When to Change Colors:
- You can change colors at the beginning of any round.
- You can change colors whenever you run out of a scrap yarn piece! This is the most “scrap-friendly” approach and creates a truly random, unique look. Just ensure you always perform the color change method above.
Part 1: The Crown (Flat Top) – Use various colors randomly!
Start with one of your scrap yarn colors.
- Round 1: Create a MR. Ch 1. Work 8 sc into the MR. (8 sc)
- Place your stitch marker in the first sc you made. You will move this marker up to the first stitch of each new round.
- Round 2: Inc in each st around. (16 sc)
- Round 3:

Sc in the next st, inc in the next st.*
Repeat from*

around. (80 sc)- Check your Crown Diameter: Lay your circle flat. For an average adult head, the crown should be approximately 6.5 – 7 inches (16.5 – 18 cm) in diameter. If it’s too small, add more increase rounds (e.g., Round 11:
*Sc in next 9 sts, inc*
– 88 sc). If it’s too large, remove a round or use a smaller hook.
- Check your Crown Diameter: Lay your circle flat. For an average adult head, the crown should be approximately 6.5 – 7 inches (16.5 – 18 cm) in diameter. If it’s too small, add more increase rounds (e.g., Round 11:

Part 2: The Sides of the Hat – Continue with random color changes
Now we’ll stop increasing and work straight down to form the body of the hat. This will cause the fabric to curve downwards.
- Round 11: Sc in each st around. (80 sc)
- Continue moving your stitch marker up to the first stitch of each new round.
- Repeat Round 11 for a total of 10-14 more rounds, or until the sides of the hat reach just above your ears. For most adults, this will be about 4-5 inches (10-12.5 cm) from the edge of the crown.
- Try on the hat as you go to get the right depth. Make sure it’s not too shallow or too deep before starting the brim.
- Change colors frequently here! Every round, every two rounds, or whenever a yarn runs out. This is where the “multicolor” really shines.
Part 3: The Brim – Continue with random color changes
The brim gives the hat its distinctive bucket shape. We’ll add increases again to make it flare out.
- Brim Round 1:
*
Sc in the next 9 sts, inc in the next st.*
Repeat from*
to*
around. (88 sc) - Brim Round 2: Sc in each st around. (88 sc)
- Brim Round 3:
*
Sc in the next 10 sts, inc in the next st.*
Repeat from*
to*
around. (96 sc) - Brim Round 4: Sc in each st around. (96 sc)
- Brim Round 5:
*
Sc in the next 11 sts, inc in the next st.*
Repeat from*
to*
around. (104 sc) - Brim Round 6: Sc in each st around. (104 sc)
- Final Round (Optional for a firmer edge): Sc in each st around. (104 sc)
- You can add or remove Brim Rounds to make your brim wider or narrower. Just make sure to finish on a non-increase round for a smooth edge.
- Fasten Off: After your final round, sl st into the next st to create a seamless finish. Cut your yarn, leaving a 6-inch tail. Yarn over and pull the tail completely through the loop on your hook. Pull tight to secure.

4. Finishing Your Multicolor Bucket Hat
- Weave in ALL Ends NEATLY (THE MOST IMPORTANT STEP!): This is absolutely crucial for a polished, professional-looking hat, especially with all the color changes.
- Use your yarn needle to carefully weave in every single yarn tail on the inside of your hat.
- Tip for weaving in: Don’t just weave in one direction. Go back and forth through stitches for about 1-2 inches (2.5-5 cm) in a few different directions to truly secure the end and prevent it from popping out. For color changes, try to weave the tail into stitches of the same color if possible, to make it less visible.
- This step will take time, but it’s worth it for a durable and beautiful hat.
- Blocking (Optional but Recommended for Cotton): Blocking can significantly improve the shape and drape of your hat, especially if you’re using cotton yarn.
- Gently wet the entire hat.
- Place it over a bowl, ball, or wig head that’s roughly the size of your head to help it dry in the correct shape. You can also stuff it lightly with plastic bags or towels.
- Gently shape the brim as desired (flat, slightly upturned, or downturned).
- Allow it to air dry completely. Blocking helps to even out your stitches and gives the hat a more crisp, professional appearance.
5. Tips for a Unique & Sturdy Scrap Yarn Hat
- Embrace the Randomness: The beauty of a scrap yarn project is the unique color combination. Don’t stress too much about perfect color transitions; the eclectic look is part of its charm!
- Yarn Management: Keep your different color scraps organized as you work.
- Consistent Tension is Still Key: Even with color changes, try to maintain a consistent tension throughout your single crochet stitches. This ensures the hat holds its shape well.
- Trying On: Regularly try on the hat as you work the side and brim sections to ensure it’s the right depth and the brim flares out as you like.
- Experiment with Color Intervals: You could change colors every single round, every two rounds, or even every few stitches within a round if you’re feeling adventurous and want a “pixelated” look (though this will create even more ends to weave in!).
- Sturdy Brim: If your brim seems a bit floppy, you can:
- Add an extra non-increase round to the brim.
- Work the last round or two in slip stitches (very dense and firm).
- Work a round or two in reverse single crochet (crab stitch) for a sturdy, rope-like edge.

Enjoy the process of turning your yarn scraps into a stylish and one-of-a-kind bucket hat, perfect for the sunny Phnom Penh weather!
