Summary of the Tutorial (Crocheted Bikini Bottom)

The video teaches how to crochet a semi-thong bikini bottom. It uses stitch patterns that help control fit and shape, then adds round elastic and optional decorative hardware/branding.

It also includes:

  • Sizing guidance based on height (cm)
  • Yarn selection for swimwear
  • Detailed steps for:
    • Front construction
    • Back construction
    • Waistband/leg elastic insertion
    • Finishing

Artistic / Creative Techniques & Concepts Shown

Garment patterning by measurement

  • Bikini bottom sizing is determined by bottom height (cm).
  • Stitch counts and row planning vary by size.

Yarn selection for swimwear

  • The tutorial recommends yarn that doesn’t retain water heavily and helps maintain shape.
  • Cléia is used as the base yarn, worked as two strands.
  • An alternative yarn (“Raí”) is discussed.
  • A yarn type that is not recommended due to a fuzzy/fluffy texture is mentioned.

Tension / stitch-flexibility control

  • Needle size is adjusted based on how tightly or loosely the crocheter works.
  • Goal: fabric that remains comfortable and flexible.

Shaping with controlled increases/decreases

The front and back are shaped using:

  • Elongated double crochet (and elongated treble crochet) for texture and structure
  • Increases at specific points to form the opening/high-cut geometry
  • Decreases to thin the back center and taper into the semi-thong shape

“Don’t increase into the chain space” aesthetic

  • Increases are placed in stitches before/around turning chains (instead of directly in chain spaces) to keep the fabric looking neater.

Elastic integration by crocheting over it

  • The waistband and leg openings are finished with a round of elongated double crochet.
  • Elastic is threaded inside the stitches.
  • The tutorial stresses preventing elastic from slipping by using:
    • proper anchoring
    • knotting
    • coverage with subsequent stitches

Customization / fit adjustment

  • Elastic size guidance is based on leg/waist measurements.
  • Tips are provided for bringing sides together without unwanted bunching, while keeping the layout symmetrical.

Materials / Tools Mentioned

  • Crochet hook/needles
    • Noted size example: 2.5 mm
    • Alternatives discussed: 2 mm and other small/larger options
  • Scissors
  • Measuring tape
  • Yarn
    • Cléia (used as two strands)
    • Alternative discussed: “Raí”
    • Not recommended: a yarn described as fuzzy/fluffy
  • Round elastic (ideal noted: 2 mm)
  • Lighter (for sealing cut elastic ends)
  • Needle (for weaving/finishing)
  • Decorative piece/label
    • A metal charm/logo (zamac) placed on the back

Step-by-Step Construction (Organized)

1) Front / base foundation and yarn setup

  • Choose yarn and work in two strands.
  • Use a measuring tape to confirm size by height (cm).
    • Example mapping given: S/M/P/G based on height ranges.
  • Create a foundation chain:
    • 10 chains for S or M
    • 12 chains for L
  • Crochet the initial rows using elongated double crochet.
    • Aim for exactly 10 stitches by the completion of the round/row structure.
    • If you reach 11+ stitches, correct it.

2) Build the front body with rows and shaping

  • Turn and begin the next rows with a single crochet edge stitch for alignment.
  • Work several rows of elongated treble crochet into the base stitches.
    • No increases during this initial section.
  • Add increases later:
    • Increases are made by adding extra stitches at the beginning and end of designated rows.
    • The tutorial avoids increasing into turning chains for a cleaner look, preferring increases in nearby “real” stitches (e.g., second-to-last instead of last-chain space).

3) Create the high-cut / opening geometry

  • The front opening is built by alternating:
    • rows with increases
    • rows without increases
  • Then, eventually continue with all increases once the opening strategy begins.
  • Height planning:
    • Measure up to where the waistband/waist elastic will start (since the band causes shrinkage).
  • Fit rule of thumb:
    • Make the base ~1 cm larger to account for elastic shrink.
    • If the elastic is tight or fit is difficult, allow 1–2 cm larger depending on desired tightness.

4) Finish and create the side chain “cord”

  • After reaching the required front height:
    • Make a chain section to form the side/strap length.
  • Chain counts are provided roughly by size range, for example:
    • smaller: 70–75
    • medium: 85–90
    • large: 100–105
  • Leave ends ready for attaching to the back.

5) Build the back (taper + semi-thong shape)

  • Attach back construction from where the front ends.
  • Use decreases to narrow the back center:
    • Decrease method uses passing loops together via the crocheter’s described technique.
  • Continue with elongated treble crochet rows without increases for a thin/taper segment.
  • Shape into a back opening triangle using increases on each side:
    • More increases → larger/taller triangle
    • Fewer increases / alternating increase pattern → smaller triangle / thinner back
  • Match the number of rows of the opening to the front for visual balance.

6) Join the front and back sides

  • Attach the back side chain/cord to the front bikini edges.
  • Ensure the attachment is straight and not twisted.
  • The creator may remove/undo a stitch if needed to rethread onto the hook for a cleaner join.

Waistband and Leg Elastic Insertion (Detailed Technique)

7) Waistband elastic

  • Work a full round of elongated double crochet around the waistband edge, stitching over the stitched edge.
  • Thread round elastic (2 mm ideal) through the stitch channel.
  • Elastic finishing:
    • Temporarily glue small ends to prevent fraying or shifting.
    • Leave ends for the waistband seam (about 1 cm overlap mentioned).
  • Distribute/gather at side points:
    • The tutorial emphasizes light gathering only on the side straps, keeping the front/back panel flat.
  • Anchor securely:
    • Knotting and multiple passes are used/encouraged so elastic doesn’t slip.

8) Seal elastic ends and cover the elastic channel

  • Cut excess elastic ends.
  • Use a lighter to seal frayed tips.
  • Continue crocheting over the elastic to hide it.
    • Stitch placement guidance is provided (e.g., using two stitches in the same hole when needed).

9) Leg openings elastic

  • Repeat the same elastic concept for the leg openings:
    • Crochet single crochet around the chain/channel edges
    • Distribute and secure elastic inside
    • Use coverage strategy that may alternate between 2 or 3 single crochets per position depending on desired coverage and opening size.

Optional Finishing and Branding

  • Add a decorative metal charm/label (zamac) at the back center.
  • The tutorial references adding lining using another lesson/video (not fully taught in this one).
