What You Need:

  • 1/3 m nylon fabric
  • Two triangle bikini inserts
  • Pin
  • Fine-tipped marker
  • Needle and thread

Steps You Need To Follow:

  1. Take 1/3 m of nylon fabric swimsuit material and use two triangle bikini inserts from an old bikini.
  1. Begin with folding the fabric in half using the two sides together. Place the inserts on top about one inch away from the fold.
  1. The fold becomes the center line of the bikini top.
  1. Next, pin around the inserts to hold the fabric together and roughly figure out the size of the bandeau top.
  1. Start to draw out the scallop edges using a finely tipped marker. The scallops can be of ½ an inch in length and about 1/3rd inch in width.
  1. You can create about five scallops. Make sure that they are cut in a straight line and not in a round shape.
  1. After you have roughly made about 11 in out from the center, begin sloping downwards to create the tie.
  1. The top and bottom of the bikini should be symmetrical. Fold your fabric in half, lengthwise.
  1. Re-pin the fabric together and start cutting out the scallop edges. After that, cut down a slight angle until you reach the folded edge.
  1. Next, take a few scrap fabric and fold it in half. Then again cut it in half lengthwise.


  1. Hold it together using a few pins.
  1. Make an inside lining piece to hold the inserts in place. Make sure that the fabric is wide enough to cover both the triangle inserts but not longer than the scallop piece.
  1. Next, use more scrap fabric to cut off a small rectangle. Sew it to each side of your inserts to connect them together.
  1. Then place the inserts in the middle between your large and small piece. Sew around your inner lining piece so that the inserts do not fall out.
  1. Gather the bandeau in the middle. Make use of another scrap fabric piece and cut it into a long rectangle about 3 inches by 6 inches. Fold it lengthwise in thirds to hide the raw edges.
  1. Wrap it around the center of the bandeau until it is tight.
  1. Cut off extra length and stitch the ends together on the inside. Now your scallop bikini is ready to be tied up.

  1. Now, iron on the opposite side until the tape becomes invisible.
