Your Starting Point

You want something small to finish today — not a blanket that eats your whole month, not a sweater with a gauge swatch standing between you and the fun part. Just one bloom, start to finish, before your coffee goes cold.

That is exactly what this crochet flower keychain pattern is built for. Five rounded petals grow straight out of a single magic ring in two quick rounds, no counting past thirteen, no chart to decode. Clip it to a bag, a lanyard, or a set of keys, and it holds its shape because cotton yarn does the structural work for you.

Below is the pattern written out in full — every stitch count, five diagrams for the moments where your hands need to see the shape rather than read about it, and the finishing notes that turn a flat bloom into a keychain that will not fall apart in your bag.

Section 1 · The Project

What You’ll Make: A 5 Petal Crochet Flower

This crochet flower pattern makes a flat, gently cupped bloom about 7–8 cm (3 in) across, worked in 5-ply cotton with a 3.5 mm hook. It is small enough to swing from a keyring and sturdy enough to survive being dropped on the sidewalk, which is more than you can say for most yarn projects. The whole thing is two rounds: the first lays down five looped petal bases from a magic ring; the second wraps each base in a fan of taller stitches so the petals puff into a proper rounded shape instead of sitting flat like a starfish.

Anatomy of the finished crochet flower keychain: magic ring center, petal base, petal side, and the 7-dc fan at the petal tip.

Round 1: five petal bases, each a 5-chain loop worked back with 4 single crochets and anchored with a slip stitch.
Round 2: each petal rounded with a climb of sc–hdc–dc, a 7-double-crochet fan at the tip, and a dc–hdc–sc descent.
Stitches used: magic ring, chain, single crochet, half double crochet, double crochet, slip stitch.
Finished size: roughly 7–8 cm across with the stated yarn and hook; thinner cotton shrinks it toward a charm, bulkier yarn grows it toward a coaster.
Uses: keychain, bag charm, appliqué, garland link, hair-clip topper, or a brooch with a pin back glued on.

If you’ve made the crochet heart keychain already, this pattern will feel familiar — same category of quick, sturdy, single-sitting project, just five petals instead of one bump. Good next project either direction.

Stitch key

mr magic ring · ch chain · sc single crochet · hdc half double crochet
dc double crochet · sl st slip stitch

Stitch height comparison for the crochet flower pattern: slip stitch, single crochet, half double crochet, and double crochet stacked from shortest to tallest.

US terms throughout. If you crochet in UK terms, treat every sc as a UK dc, every hdc as a UK htr, and every dc as a UK tr — the stitch counts stay identical, only the names shift.

Yarn choice matters more than color. Cotton holds the petal shape crisply and blocks flat, which is what you want on a keychain that gets handled daily. A soft acrylic will still bloom, just puffier and rounder at the tips.

Section 3 · Round 1

Round 1: The Five Petal Bases

Everything grows out of one magic ring. Each petal base is a small loop: chain out five, skip the chain nearest the hook (that skipped chain becomes the petal’s tip loop), work four single crochets back down the chain, and anchor the petal with a slip stitch. Do that five times and the flower’s skeleton is complete — five loops fanned around a closed center, ready for shaping.

Make a mr and ch 1 to secure it.
1 sc into the mr.
Ch 5.
Skip 1 ch (the one closest to the hook), then work 4 sc into the next four chains, working back toward the ring.
Sl st into the ring to anchor the petal.
Repeat steps 2–5 four more times, for five petal bases total (1 sc into the mr, ch 5, skip 1 ch, 4 sc, sl st).
Pull the tail to close the magic ring tight.
Sl st into the first sc to join the round.

Count your bases before Round 2. You should see exactly five looped petals around a closed center. Four or six means it is far cheaper to fix now — rip back one petal base in seconds — than to unpick a fully shaped bloom later.

Closing order matters. Pull the tail tight before the joining slip stitch. Close the ring after joining instead, and a small gap sits behind, right where the tip of every petal meets.

Section 4 · Round 2

Round 2: Shaping the Petals

This is the round where the flower stops looking like a starfish and starts looking like a bloom. Stitch height does the sculpting: short stitches at the base of each petal, a wide fan of seven double crochets spreading across the tip loop, then the mirror image back down. Thirteen stitches per petal, five petals, and no counting beyond that.

1 sc into the first stitch of the petal base.
1 hdc into the next stitch.
1 dc into the next stitch.
7 dc into the tip loop (the skipped chain space) — this fan rounds the petal’s outer edge.
1 dc into the next stitch, 1 hdc into the next, 1 sc into the last — the mirror descent.
Sl st into the ring at the base of the petal to lock it in place.
Repeat the full sequence on the remaining four petals.
Sl st to the first sc, ch 1, and cut the yarn, leaving a 15 cm tail for weaving.

Let the fan breathe. Work the 7 dc with a relaxed hand. Pulled tight, the fan cups the petal into a taco shape; kept easy, it opens into the broad, rounded tip you want on the finished flower.

Petals twisting or overlapping? Make sure each sl st lands in the ring between petals, not into the top of a petal stitch. That anchor point is what keeps all five petals pointing outward instead of stacking on top of each other.

Section 5 · Finishing

Finishing: Hiding the Tails & Adding a Keychain

Two tails exist on a finished flower: the magic-ring start and the final join. Weave both across the back of the center, change direction once partway through, and trim flush so nothing works its way loose after a few trips in and out of a bag.

Thread the tapestry needle with the first tail.
Weave under three or four stitches on the back of the flower, close to the center.
Turn a corner and weave back through a different path, then pull gently and trim flush.
Repeat with the second tail.
Attach a ball chain or jump ring through the edge of one petal (or between two petals, right at the center) to finish it as a keychain.

Flatten it for appliqués. If the flower is headed onto fabric instead of a keyring, press it under a heavy book for an hour, or hover steam over it briefly, so the petals lie flat and neat before you stitch it down.

When It Goes Sideways

Troubleshooting: Quick Fixes

Problem	Likely cause	Fix
Four or six petals instead of five	Lost count of the base repeat	Count bases before Round 2; add or rip one base now
Hole in the center	Tail pulled after joining	Pull the tail first, then sl st into the first sc
Petals cup like tacos	7-dc fan worked too tight	Relax tension; block flat under a book or light steam
Petals twist or overlap	Sl st landed on a petal stitch	Anchor between petals, into the ring itself
Tails pop back out	Single-pass weaving	Weave, turn a corner, weave again, trim flush
Flower looks small or oversized	Hook/yarn mismatch	Match a 3.5 mm hook to 5-ply cotton for the 7–8 cm size in this pattern

Crochet Flower Keychain Questions, Answered

How big is the finished crochet flower keychain?

About 7–8 cm (3 in) across with 5-ply cotton and a 3.5 mm hook. Thinner yarn and a smaller hook shrink it toward a 5 cm charm; bulkier yarn grows it into a coaster-sized bloom instead.

I don’t have 5-ply cotton. Can I still make it?

Yes. Any smooth yarn works — just match the hook to the yarn weight. The pattern’s shape comes from stitch heights, not from the fiber, so acrylic, bamboo, or wool all bloom the same way.

Why does the pattern skip one chain on every petal base?

The skipped chain leaves a small loop at the petal’s tip. In Round 2, the fan of 7 dc spreads into that loop, which is what rounds out the petal instead of leaving it pointy at the end.

Is this crochet flower pattern suitable for a first-time crocheter?

It’s a strong second project. You’ll need the magic ring plus sc, hdc, dc, and slip stitch — and because the flower is flat and quick, every stitch stays visible while you learn which height feels like which.

How do I turn it into a keychain instead of an appliqué?

Thread a ball chain or small jump ring through the edge of one petal, or between two petals at the center, and close it. For a sturdier anchor, sew a tiny fabric or ribbon loop to the back first.

My flower curls instead of lying flat. What now?

Usually that’s tight tension in the 7-dc fans. Loosen your hand on the next flower, and rescue the current one by pressing it under a heavy book for an hour or holding steam over it briefly.

Can I make this 5 petal crochet flower bigger for a coaster or brooch?

Yes — go up a hook size or two (4–4.5 mm) with the same 5-ply cotton, or switch to a worsted-weight yarn. The stitch counts stay identical; only the finished size grows with the hook and yarn.

How much yarn does one flower actually use?

Well under 5 meters of 5-ply cotton per bloom, so a single 50g ball realistically makes a dozen or more flowers in one color, with plenty left for the next project.

One Bloom Down, a Bouquet To Go

Run the checklist one last time before you knot off:

Magic ring made, ch 1 to secure it.
Five petal bases: 1 sc, ch 5, skip 1 ch, 4 sc, sl st.
Tail pulled tight before the joining slip stitch.
Every petal shaped: sc–hdc–dc up, 7 dc fan, dc–hdc–sc down, sl st.
Joined to the first sc, ch 1, yarn cut.
Both tails woven, turned, and trimmed flush.
Keychain hardware or pin back added — optional but tempting.

Now make the next one in a different color, and the next after that. At ten minutes a bloom, a whole keyring’s worth of flowers fits inside a single quiet evening — and not one of them will ever need watering.
