What You’ll Need: Materials Table

|---|---|---|
| Yarn | Cotton or cotton blend, worsted weight | 200-300g in 2-3 colors |

Step-by-Step: How to Crochet the Granny Square Bucket Hat
Step 1: Crochet the Granny Squares
- Make a magic ring or chain 4, joined into a circle, for each square.
- Work the first round with 3 double crochet groups separated by chain-3 corners.
- Continue adding rounds, changing colors as desired, until each square reaches the target size.
- Repeat until you have the number of squares needed for your size.
Step 2: Join the Squares into the Hat Band
- Lay your squares out in a row to plan your color pattern
- Join the squares along their side edges using slip stitch or a whip stitch seam
- Continue until the row forms a complete circle for the sides of the hat
- Double-check the joined circle fits comfortably around the head before continuing
Step 3: Crochet the Crown
This is where the hat starts feeling like an actual hat instead of a strip of squares:
- Crochet one larger granny square, slightly bigger than your side squares, for the crown.
- Round the corners slightly with extra stitches if you want a smoother circular shape.
- Join the crown to the top of your assembled side band, easing in the corners evenly.
- Secure with a whip stitch or slip stitch seam around the entire edge.
Step 4: Add the Brim
- Work rounds of double crochet from the bottom edge of the side band, increasing evenly
- Continue increasing until the brim lays flat and reaches your desired width
- Finish with a simple single crochet edge for a clean, defined border
- Weave in all loose ends securely
Tips for a Clean, Boutique-Style Finish
- Keep tension consistent across all squares so they join without puckering
- Use stitch markers to track corners while joining, especially on your first hat
- Choose 2-3 colors max for a cohesive look, or go scrappy for a fun, eclectic style
- Steam block the finished hat lightly to help the brim lie flat
Common Mistakes to Avoid
- Uneven square sizes — leads to a lumpy, misaligned band once joined
- Skipping the fit check — always test the joined band against the head before adding the crown
- Rushing the brim increases — uneven increases cause the brim to ripple or cup
- Ignoring yarn choice — acrylic yarn can feel hot and heavy for a summer sun hat
