Pattern Notes

• Work in continuous rounds unless specifically instructed otherwise.
• Use a stitch marker to keep track of your starting stitch for each round.
• Employ an invisible finish for neatness at the end of completed circles.
• When joining layers, always work through the back loop only (BLO) for crisp, stacked edges.
• You will not sew parts together—layers and fillings are attached by crocheting or embroidering directly onto your work.
• For custom hamburgers, mix up “ingredient” layers or ruffle stitches as you please.

2. With red yarn (tomato), attach in the BLO of any stitch (through both buns) at “joining edge.”
   • Insert hook through BLO of patty AND BLO of bottom bun in the same spot.
3. Ch 1 to secure.
4. As you go around:
   • Work randomly [sc, hdc] or [sc, dc] or 2 sc in some sts to create a ruffled/wavy edge, always through both layers’ BLO.
   • Example: In first st, sc and hdc; in next, hdc and sc; next, dc alone; next, 2 hdc in one st.
   • Continue for about ⅓ or ½ of the round (for tomato slice look).
5. Color change to green (lettuce): In the final YO of last tomato stitch, draw up green yarn.
6. Continue working [sc, hdc, dc, 2 sc] in green to create the rest of the ruffled/wavy edge.
7. Leave a small opening; stuff hamburger with polyester filling.
8. Finish closing by working remaining stitches with ruffles to the starting point.
9. sl st to join. FO, pull through, and using needle, hide the tail inside.
