About this pattern

This pattern makes a small crocheted straw-style hat worked in single crochet (UK: double crochet) with a 2.5 mm hook and 100% cotton yarn. Construction starts at the crown with an adjustable ring, increases from eight to twenty-four stitches, then continues through the remaining rounds before fastening off and folding the brim into shape.

This mini crochet straw hat is worked entirely in single crochet (UK: double crochet), the tight, dense stitch that gives amigurumi and small accessory patterns their firm structure. The finished piece sits in the same family as crochet baskets and other miniature hats used as doll accessories or decorative props, where a small stitch and a fine hook keep the fabric close enough to hold its shape without stiffening spray or wire.

Construction begins at the crown with an adjustable ring closed by pulling the yarn tail, then builds outward in continuous rounds of single crochet increases, expanding from eight stitches to twenty-four as the brim widens. Rounds are joined with a slip stitch rather than turned, keeping the fabric flat and even. Once the working rounds are complete the piece is fastened off, the tail woven in, and the brim folded down where the sides end to give the hat its finished curve.

    Round 4

    Chain one. Pattern: one single crochet, then an increase. Repeat around (36 stitches).Slip stitch to join.

  3. Rounds 5–9

    Building the Sides For five rounds, do one single crochet in each stitch. Start each round with a chain one and join with a slip stitch.

This forms the sides of the hat.

  2. Step 2Fold the brim down where the sides end and gently shape the hat.

Notes from the pattern

  • Use the 2.5 mm hook with the 100% cotton yarn specified in the materials; a looser hook-to-yarn match will produce a floppier hat that will not hold the folded brim shape as well.
  • Rounds are slip-stitch joined and restarted with a chain one, so count stitches after each increase round to confirm the sixteen and twenty-four totals before continuing.
  • No stitch markers are listed in the materials, but marking the join point in early rounds makes it easier to track the increases from eight up to twenty-four stitches.
  • The pattern uses a single colour of cotton yarn throughout, so no colour changes or carrying of a second strand are needed at any round.

Stitches you will use

  • Adjustable ring start Used to begin the crown; the yarn is wrapped twice around a finger, the hook inserted under both loops, and a chain one secures it without counting as a stitch. Watch that the tail pulls the ring fully closed before working the first round.
  • Continuous spiral rounds Used throughout the crown and brim, with each round joined by a slip stitch and restarted with a chain one rather than turning. Watch for stitch count drift between rounds, since there is no seam to catch a missed stitch.
  • Single crochet increase (UK: double crochet increase) Used in the round that doubles stitches evenly and in the following round's one-then-two pattern to grow from eight to sixteen to twenty-four stitches. Watch that increases land in the correct stitch so the repeat stays even around the circle.

Troubleshooting

The crown cups upward instead of lying flat after the increase rounds.

This usually means the ring was not pulled fully closed or the increases landed unevenly around the circle; snug the tail before starting the increase rounds and check for the correct stitch count at each join.

The brim ripples or waves at the edge instead of sitting flat.

This points to an uneven or over-loose increase pattern; recount stitches after the twenty-four-stitch round, work with slightly firmer tension, and gently reshape the finished piece by hand.

The sides will not hold their shape when folding the brim down.

This happens when the fasten-off and tail-weaving are skipped or done too loosely before folding; secure the tail firmly first, then fold and shape while the fabric is under slight tension.

Substituting yarn

Mercerised cotton, same weight as specified
Adds a subtle sheen closer to a woven straw look while keeping the same 2.5 mm hook and firm, unstuffed structure.
Linen-cotton blend, light fingering weight
Gives a crisper drape and texture that reads more like natural straw; a slightly smaller hook may be needed to keep the fabric equally tight.
Acrylic, light worsted weight
Produces a softer, less structured hat; working with firmer tension or a slightly smaller hook helps compensate for the fibre's extra give.

Washing and care

  • Hand wash the finished hat in cool water only when needed, since the 100% cotton yarn holds its shape well but can shrink slightly if washed or dried with heat; lay flat to dry rather than hanging.
  • Reshape the folded brim by hand while the piece is still slightly damp, then store it flat or over a small support so the curve does not flatten out over time.

FAQs

Questions

What hook and yarn does this hat need?

A 2.5 mm hook and 100% cotton yarn are used throughout, as listed in the materials. This combination keeps the single crochet stitches tight enough for the finished hat to hold its shape.

How many rounds does the hat take to complete?

The main pattern piece is listed as six worked rounds, with the assembly step noting that fastening off happens after round 14. Both figures come from the pattern as written, so it is worth checking the round-by-round instructions directly for the full sequence.

Why does the yarn wrap twice around a finger at the start?

This creates the adjustable ring with a doubled loop, giving a more secure closure than a single wrap. The hook is inserted under both loops and a chain one locks it in place before the first round is worked.

Does the hat need any stuffing?

No, the materials list does not include stuffing or fibrefill. The hat's structure comes from the stitch tension, the cotton yarn's natural body, and the fold at the brim.

How is the brim shaped once the crochet is finished?

After fastening off and weaving in the tail, the brim is folded down at the point where the sides end and shaped gently by hand. No blocking tools or pins are specified in the pattern.
