About this pattern

A three-part crochet hamburger keychain: a two-round top bun, one-round base bun, and one-round cheese square, each made separately then layered and glued. The top bun starts in a magic ring of six single crochets, uses an invisible decrease, and gets lightly stuffed; the base bun repeats the setup in back-loops-only. Cheese is worked in half double crochet rows. Meat and tomato patterns are separate.

This hamburger keychain builds from three separate pieces — a two-round top bun, a one-round base bun, and a one-round cheese square — each worked to shape before assembly. The top bun starts with a magic ring of six single crochets, decreases using an invisible-decrease trick worked into the front and back loops, and gets lightly stuffed before closing. The base bun repeats the same setup worked in back-loops-only (BLO) for a flatter profile. Cheese comes together in half double crochet rows. Meat and tomato pieces are separate patterns, glued on after crocheting is done.

The pattern

Written out round by round

Materials

Worsted weight yarn
Crochet hook (size to suit your yarn)
Yarn in your choice of colors (yellow shown for the cheese square)
Stuffing (to lightly stuff the top bun)
Glue (to assemble the finished pieces together)

Abbreviations

blo = back loops only

Top Bun

Round 1Create a magic ring with six single crochets.

Rounds 2–3Rounds 2 and 3: Continue crocheting using the join-as-you-go or spiral method.Use an invisible decrease trick by crocheting into the front and back loops of the next stitch.Close the round and lightly stuff the bun.

Use a different piece of yarn to add details for the bun's crust.

Base Bun

Round 1Follow the same pattern as rows 1-4 of the top bun. Continue by inserting the crochet hook into the back half of the stitch (BLO).

Cheese

Rows 1–5Continue crocheting using half double stitches for four to five rows to form a yellow square.Measure the size of the cheese to ensure it fits the bun.

Assembly

Step 1The meat and tomato pieces are separate crochet patterns, added when assembling the finished hamburger.

Step 2Layer and glue the crocheted components together to form the hamburger.

Tester's notes

6 single crochets in the starting magic ring set the top bun's finished size — miscounting here throws off shaping in rounds 2 and 3.

2 rounds shape the top bun while the base bun uses only 1 round; don't add extra rounds to the base expecting it to dome like the top.

Stuff the top bun lightly before closing; overstuffing pulls the BLO-worked base bun out of alignment once the pieces get glued together.

4 to 5 rows of half double crochet form the cheese square — stop as soon as it matches the bun's width, since the row count is a range, not a fixed target.

Gauge check

After the magic ring's 6 single crochets close, check that the ring pulls shut with no visible hole at the center; if a gap remains, cinch the tail again before starting round 2.

There's no measurement given beyond stitch counts, so judge tension by feel — stitches should sit close enough that stuffing won't show through the fabric, but loose enough that the hook doesn't fight each insertion.

If something looks wrong

The top bun looks lumpy instead of evenly domed.: The invisible-decrease trick (working into the front and back loops of the next stitch) was skipped or misplaced across rounds 2 and 3. Unravel back to the round 1 magic ring of 6 single crochets and recount before decreasing again.
The base bun curls up at the edges instead of lying flat.: The BLO round was worked into both loops by mistake. Frog the round and re-insert the hook into the back half of each stitch only, as the pattern specifies.
The cheese square doesn't line up with the bun edges.: The row count landed at one end of the 4-to-5 row range without checking fit. Measure the cheese against the base bun before stopping and add or remove a row rather than stopping at a fixed count.
The crust detail yarn shows through or: Detail stitches were added before the round was fully closed. Close the round first, then work the second yarn over the finished surface.

Yarn substitutions

Cotton, worsted weight	Holds its shape without the stuffing settling unevenly, but stitch definition shows more; size the hook down slightly for a firmer fabric.
Acrylic, worsted weight	Keeps drape soft and hides stuffing through the fabric; stitch counts (like the 6-single-crochet magic ring) behave close to standard worsted gauge, so the same hook size applies.
Bulky-weight acrylic or wool blend	Produces a larger keychain than the 6-single-crochet magic ring start implies, turns the top bun's 2-round shaping into a bigger dome, and needs a larger hook plus more stuffing to fill it out.

FAQs

Questions

Why does the base bun use only 1 round while the top bun uses 2?

The base bun sits flatter against the meat and cheese, so a single round worked in BLO gives enough surface without a dome. The top bun's second round adds the curve that makes it read as a bun instead of a disc.

Can the cheese square be more or fewer than 4 to 5 rows?

The pattern gives a range on purpose, so the cheese can be measured against the bun before stopping. Add a row if the base bun runs wide, or skip the fifth row if it runs narrow.

When does the crust detail yarn get added?

It's worked onto the surface of the top bun after the round is closed and the piece is stuffed, using a second piece of yarn. It's decorative, not part of the structural rounds.
