- 5.0 mm crochet hook
- Yarn needle
- Scissors

π How to Make a Spiral Motif:
Youβll be working 2 spirals together in different colors.
πΈ Part 1 β Starting the Spirals:
1οΈβ£ With Color A:
- Make a magic ring.
- Ch 3 (counts as dc).
- Work 6 dc into the ring.
- Do not join β you’re working in a continuous spiral.
- Pull ring closed.
2οΈβ£ Attach Color B:
- In the same magic ring, attach Color B.
- Ch 3 (counts as dc).
- Work 6 dc into the ring beside Color A stitches.
Now you have 2 spirals starting together.
πΈ Part 2 β Building the Spiral Rounds:
For Color A:
- Continue working in the first unworked front loop of each stitch made by Color A.
- Work 2 dc in each stitch around (6 increases).
- Next round, work (2 dc in next st, 1 dc in next st) repeat around.
- Next round, work (2 dc in next st, 1 dc in next 2 sts) repeat around.
For Color B:
- Repeat the same as for Color A in its stitches.

Keep alternating rounds, growing the spirals.
πΈ Part 3 β Shaping the Wave Edge:
As the spirals grow:
- The edge will naturally curve.
- Stop when each spiral section is about 4 rounds.
To finish:
- Join with a sl st to the adjacent spiral at certain points along the edge to create the wave connection.
π Joining the Spirals:
- Align two spirals edge to edge.
- Use sl st or sc through the back loops of both motifs where they meet.
- Continue adding spirals in alternating directions to form the wave chain.
π¨ Color Play:
- Alternate Color A and Color B as shown in your image.
- Or use a gradient or rainbow effect for a playful trim.
β¨ Pro Tips:
- Use a stitch marker at the start of each spiral round to keep track.
- Keep your increases evenly spaced for a smooth curve.
- Blocking the final piece will enhance the wave shape.
