Materials 

• 2.5 mm crochet hook
• Cotton yarn (Tex 295)
• Pre-shaped bikini lining (bojo)
• Yarn needle
• Scissors
• Stitch markers or substitute (extra yarn, clips)

Preparing the Lining (Bojo)

Cut and Shape the Lining

• Trim the tip of the lining into a rounded shape.
• Fold the lining, align both halves, and cut the opposite tip to match the rounded shape.

Punch Holes Around the Lining

• Use a thin hook or hole punch to make small, evenly spaced holes along the entire edge.
• Pass your hook from the inside to the outside when making holes.

Crochet Around the Lining

• Leave a long starting tail.
• Insert a slip knot and make a single crochet (sc) into the first hole.
• Make two single crochets into each hole all around.
• At the corners, work three single crochets in the same hole.
• Secure the yarn tail by crocheting over it.
• Close the round with a slip stitch.
• Cut and weave in the yarn tail, knot and trim if needed.
• Repeat the process for the second lining piece.

Crocheting the Main Fabric for the Lining

Foundation Chain

• Leave a long tail.
• Chain 20 (adjust according to your lining size).

Row 1

• Skip the first two chains.
• Work 1 half double crochet (hdc) in the third chain from the hook.
• Make 1 hdc in each remaining chain across (19 hdc total).

Rows 2–11 (No Increases)

• Chain 2, turn.
• Skip the first stitch under the chain.
• Make 1 hdc in each stitch across, always ending in the top of the previous row’s chain-2.
• Repeat for a total of 11 rows (approx. 9 cm height).

Row 12 (First Increase Row)

• Chain 2, turn.
• Work 1 hdc in each stitch.
• In the last stitch, make 2 hdc (increase by 1 stitch).

Row 13 (Second Increase Row)

• Chain 2, turn.
• Skip the first stitch, work hdc in each until second-to-last stitch.
• Make 2 hdc in the increased stitch from the previous row.

Rows 14–24 (Continue Without Increases)

• Chain 2, turn.
• Work 1 hdc in each stitch across.
• Work until the crochet fabric fully covers the lining (approx. 13 rows past increase).
• Adjust based on tension and fabric stretch.

Attaching the Crochet Fabric to the Lining

Align and Secure the Fabric

• Mark the top and corner points of the fabric with stitch markers to align with lining.

Join with Single Crochets

• Chain 1 to start.
• Insert hook through crochet fabric and corresponding lining hole.
• Make single crochets all around to attach them.
• Don’t increase along straight edges.
• At curves, work 2 single crochets in the same spot to prevent puckering.
• Carefully work through chains along the starting edge.
• Adjust tension by skipping stitches or doubling in the same space if needed.
• Join with a slip stitch to finish.

Creating the Casing for the Straps

Row 1 (Eyelet Row)

• Chain 1, turn.
• Work 2 single crochets.
• Repeat: Chain 1, skip 1 stitch, make 3 single crochets.
• Customize gaps with chain 2 or use hdc for larger openings if preferred.

Row 2 (Solid Row)

• Chain 1, turn.
• Work single crochets into all stitches and chain spaces from the previous row.

Side Strap with Tapered End

 

Edge Preparation

• Work single crochets evenly along the side edge until the bottom corner of the lining.

Begin Strap

• Chain 2, turn.
• Work 22 hdc (adjust as needed to match your lining width).

Tapering Rows

First Decrease Row:

• Chain 2, turn, skip first stitch, slip stitch into next.
• Chain 2 again and hdc across (no decrease at the end).

Second Decrease Row:

• Chain 2, turn, skip first stitch, hdc across until last 2 stitches.
• Do not work into the final chain-2 stitches.

Repeat these two rows alternately until only 2 hdc remain.
