Step-by-Step Guide to Crochet a Bikini Bottom

Step 1: Starting the Project

  • Begin by chaining a foundation chain long enough to fit the width between the two points of your bikini (from one side to the other).
  • For a medium size, the instructor starts with 40 chains. Adjust this number based on your size.

Step 2: Creating the First Triangle

  • Row 1: Start working double crochets along the chain. Begin with a double crochet in the first stitch and continue across the entire chain.
  • Row 2 and Onwards: After completing the initial row, chain 3, flip the work over, and begin the next row.
    • Decrease at the start of the row by making 2 double crochets together (2DC together).
    • Continue with regular double crochets across the row.
    • Decrease again at the end of the row by making another 2DC together, followed by 1 double crochet in the last stitch.
  • Repeat this process (chain, flip, decrease at the start and end) until the triangle takes shape. The instructor demonstrates 16 rows of decreasing for a medium size.

Step 3: Creating the Middle Section

  • After finishing the triangle, transition to the middle part, which connects and adjusts the bikini bottom to fit your size.
    • Rows Without Increasing or Decreasing: For a medium size, crochet 9 rows with regular double crochets (no increases or decreases).
    • Adjust this step depending on the desired size—more rows for larger sizes, fewer rows for smaller sizes.

Step 4: Adding Increases

  • After completing the middle section, start increasing to create the next triangle or section:
    • Increase at the Start: Chain 3 and add 2 double crochets in the same stitch.
    • Continue with regular double crochets across the row.
    • Increase at the End: In the last stitch, place 2 double crochets together.
  • Repeat the increase rows until the bikini bottom reaches the desired dimension or matches the initial triangle.
