Each one is typed out whole and gets its own line.

This brooch starts as a single long strip, chained to 81 and built up in four rows on the same piece — no joining in the round, no separate petals to sew on later. The first two rows set a flat, curved base; the last two raise shell-stitch petals along one long edge, shorter near the center and taller toward the outer edge. Once the last row is secured, the whole strip rolls inward on itself to form the rose. Have your yarn, a hook sized to it, scissors, and a yarn needle on hand before you start — nothing else is needed.

Common mistakes and their fixes

Losing count across the skip-one rhythm
Place a marker at the start of each petal group in Rows 3 and 4, since every petal depends on skipping exactly one stitch before and after it.
Treating extended double crochet like a plain double crochet
Pull up the extra loop before completing the stitch as directed — skip that step and the three middle petals in Row 4 will sit flat instead of standing taller than their neighbors.
Rolling the strip too loosely
Keep the roll tight and pin the base as you go before stitching; a loose roll leaves gaps at the center that show once the brooch is pinned on.

Main Pattern

Row 1

Tie a slip knot and chain 81; chain 1 (turning chain), skip the first chain from the hook, then single crochet in the next chain; single crochet in each chain across.

Row 2

Turn the piece over (if you didn't work into the back bumps initially, now switch so that the top of the stitches are at the bottom for a thicker and nicer look); chain 1 and slip stitch into the first stitch; chain 3 (counts as a double crochet); double crochet in the next stitch; increase by putting two double crochets in the next stitch; follow this pattern across: one double crochet in each of the next two stitches, then two double crochets in the next stitch, repeatedly; by the end, your piece should curve like a semicircle.

Row 3

Turn the piece over to create the rose petals using the shell motif pattern; chain 1, skip one stitch and put 4 half double crochets into the next stitch to create half of a petal; repeat the 4 half double crochets in the following stitch (completing the petal); skip one stitch and secure with a single crochet in the next stitch (one petal completed); skip one stitch, then make 4 half double crochets in the next stitch for the first half of the next petal, followed by 4 half double crochets in the subsequent stitch for the second half, skip one stitch and secure with a single crochet; after making two half double crochet petals, increase the height of petals by using double crochet instead of half double crochet for the next petals; skip one stitch, then make 4 double crochets in the next stitch, and so on, as you have been doing with the half double crochets; secure each petal with a single crochet after skipping a stitch; continue with 8 double crochet petals.

Row 4

After the midpoint, start increasing the size of the petals for the outer part of the rose; skip one stitch, then make 3 double crochets, followed by 3 extended double crochets, and another 3 double crochets in the next stitch; to make an extended double crochet: yarn over, insert the hook into the stitch, pull up a loop (three loops on hook), yarn over and pull through one loop (the extended loop), then complete as you would a regular double crochet; skip one stitch and secure the extended petal with a single crochet; repeat this sequence around.

Assembly, in order

Step 1After completing the last petal, slip stitch along the edges to the bottom of the flower.
Step 2Fasten off, leaving about 20 inches of yarn for sewing.
Step 3Wrap the front end and roll the strip inwards to form the rose. It should be tight and closed together.
Step 4Stitch the bottom together, securing with pins as necessary.
Step 5Secure the end to the second layer and weave in the ends to tighten the construction.
Step 6Do additional runs with the needle around the bottom to ensure its stability.
Step 7Finish off and weave in any remaining ends.

Check these before you start

  • Hook size is yours to choose, but keep it consistent across all four rows — a looser hook on the petal rows will make the shells flare instead of cupping.
  • Mark the first stitch of each row with a scrap of contrasting yarn or a stitch marker; the skip-one-stitch rhythm in Rows 3 and 4 is easy to lose without one.
  • Tension matters most on the extended double crochets in Row 4 — pull the extra loop to the same height as a regular double crochet, or that outer petal will sit uneven against its neighbors.

Set-up

  • Confirm you have enough yarn for a chain of 81 stitches plus four full rows of petal shaping — this strip is long before it is rolled.
  • Match your hook to the yarn weight you have chosen; the pattern gives no fixed size, so swatch a few rows of single crochet to check the fabric isn't stiff or sloppy.
  • Read Row 2 in full before turning your foundation row — the dc-dc-2dc increase sequence is what shapes the semicircle, and it is easier to follow once before working it.
  • Set aside a 20-inch tail at the end for sewing; plan your fasten-off with that length in mind rather than cutting short.

Construction

The increases in Row 2 — one double crochet, one double crochet, two double crochets, repeated across — are what turn a straight foundation row into the curved semicircle the petals sit on.

The piece is worked flat rather than in the round because it is meant to be rolled afterward: each row adds a taller band of petals along one edge, and rolling the finished strip is what turns a flat shell pattern into a dimensional rose.

Time per section

Foundation and base curve (Rows 1-2)about 30-40 minutes because it is a long chain-81 row plus one shaping row
Shell petals (Rows 3-4)about 2-3 hours because each petal is built from multiple stitches into one base stitch and needs a steady skip-one rhythm
Rolling and finishingabout 1 hour because the roll must be pinned, stitched, and reinforced with extra needle passes for stability

Common questions

Why does Row 2 need to be worked right after turning the foundation row?
Row 2 is what shapes the straight chain-81 base into a curved semicircle using the dc-dc-2dc increase sequence. Skipping or rushing this row leaves the base too straight for the petals to roll into a round rose later.
How tight should the roll be in the assembly steps?
Tight and closed together, as the assembly steps specify, with the bottom pinned before stitching. A loose roll will not hold its shape once pinned to fabric.
