Here is a step-by-step tutorial to make the linked half-circle crochet border shown in the image. This pattern creates overlapping arches that look beautiful for edges, straps, or decorative trims.
π CROCHET LINKED ARCHES BORDER β FULL DETAILED TUTORIAL
US crochet terms
β 1. FOUNDATION
Step 1 β Make a slip knot
Place it on your hook.
Step 2 β Chain 10
This chain creates the first arch.

β 2. FIRST ARCH
Step 3 β Double crochet into the 5th chain from hook
- Count: the 4 skipped chains = act as 1 DC + 1 chain-space.
- Into the 5th chain, work:
π 10 double crochet (DC) into the SAME chain.
You will now have a half-circle shape.
β 3. CREATING THE JOIN FOR THE NEXT ARCH
This is what makes the arches interlock.
Step 4 β Chain 5
This is the new archβs base chain.
Step 5 β Slip stitch (sl st)
Insert your hook into the side of the arch:
β‘ Locate the space between the last 2 DC stitches from the arch.
β‘ Insert hook through both loops (or through the gap).
β‘ Make 1 slip stitch to attach the chain to the arch.
Step 6 β Chain 3
This works as βheightβ for the coming DC stitches.

β 4. SECOND ARCH
Now you build the next half-circle directly on the arch, not in a chain.
Step 7 β Work 10 DC into the attachment point
Into the same space where you made the slip stitch:
πΈ Yarn over
πΈ Insert hook into the same space
πΈ Make 10 double crochet
As you complete them, they naturally form a curved shape that overlays the previous arch.
You now have 2 linked arches.

β 5. REPEAT FOR ALL REMAINING ARCHES
For each new arch:
Step A β Chain 5
(This forms the next loop.)
Step B β Slip stitch into the top-side of the previous DC group
Insert hook into the small gap at the top of the previous arch.
Step C β Chain 3
Step D β 10 DC into the same joining point
Repeat Steps AβD for the whole length you want.

β IMPORTANT NOTES FOR SCULPTED, NEAT ARCHES
β Keep tension even
Loose is better than tight.
β Always insert in the same gap
This ensures the arches overlap smoothly.
β Block finished piece
Light steam or pin-and-spray shaping will make the arches open and align beautifully.
π OPTIONAL β MAKE ARCHES BIGGER OR SMALLER
You can resize it:
To make bigger arches:
- ch 12 at the start
- skip 5 ch
- do 14β16 DC per arch
To make smaller arches:
- ch 8 at the start
- skip 3 ch
- do 8 DC per arch
