That crochet pattern in your image is called a crochet scallop (or wave) strip β it creates a wavy, bumpy edge often used for decorations, edgings, headbands, or scarves. Hereβs how to make it step-by-step:
π§Ά Crochet Scallop Wave Strip Tutorial (Step-by-Step)
β¨ What You Need
- Yarn: Medium-weight (size 3 or 4) cotton or acrylic
 - Hook: 3.5 mm to 4 mm (match to yarn thickness)
 - Scissors
 - Tapestry needle for weaving in ends
 

πΌ Step 1: Foundation Chain
- Chain 17 stitches (or any multiple of 6 + 5, depending on desired width).
- Example pattern repeat: 
(6 Γ number of waves) + 5 - 17 chains = 2 full waves + 1 half wave.
 
 - Example pattern repeat: 
 
πΈ Step 2: Row 1 β The Base
- Start in the 4th chain from the hook.
 - Make 1 double crochet (dc) in that stitch.
 - Continue making 1 dc in each chain all the way across.
 - You should have 15 dc total (including the first chain 3 as one dc).
 - Turn your work.
 
πͺ This row forms the base foundation for your scallops.

πΊ Step 3: Row 2 β Forming the Scallops
- Chain 1 (turning chain).
 - Skip 2 stitches, then make 5 dc in the next stitch β this creates the first scallop βbumpβ.
 - Skip 2 stitches, then 1 single crochet (sc) in the next stitch β this anchors the scallop.
 - Repeat steps 2β3 all the way across:
- Skip 2, 5 dc in next, skip 2, sc in next.
 
 - End with 1 sc in the last stitch.
 - Turn your work.
 
π§΅ Now youβll see a wavy line forming!
π· Step 4: Row 3 β Offset Scallops
This row fills in the gaps to create alternating waves.
- Chain 3 (counts as 1 dc).
 - Make 2 more dc in the same stitch β this forms half of a scallop at the start.
 - Skip 2 stitches, 1 sc in next, skip 2, 5 dc in next stitch.
 - Repeat from * to * across.
 - At the end of the row, instead of 5 dc, make 3 dc in the last stitch (to finish the half scallop).
 - Turn your work.
 
πͺ You now have a perfect offset scallop pattern β just like the picture!

π» Step 5: Repeat for Length
- Repeat Row 2 and Row 3 alternately until the strip reaches your desired length.
 - Keep your edges neat by always chaining 1 or 3 correctly when turning.
 

πΌ Optional Finishing (Headband or Edging)
- For a headband, stop when your piece is about 45β50 cm (for adult size).
 - Join ends with slip stitch or sew together using a tapestry needle.
 - You can also make two strips and sew them side by side for a thicker headband.
 
π‘ Tips
- Tighter tension makes crisper waves.
 - Lighter yarn gives a more delicate, lace-like look.
 - Heavier yarn gives a thicker, puffier design.
 - Try using two colors alternating every 2 rows for a striped scallop look!
