Things You'll Need
Instructions
Measure your bust, hips and waist. Go to a fabric store in your area to buy a bikini pattern, fabric and the necessary notions listed on the back of the pattern.
Cut out the pattern pieces on the line corresponding with your size. Fold the fabric in half and pin on these pieces as indicated in the manual. Mark any notches and darts, and cut out the front and back pieces of your custom bikini bottom.
Pin the wrong sides of these two pieces together, matching the notches. Thread your sewing machine, and sew these two pieces at the sides.
Use the guide to cut a piece of elastic and mark it as directed. Sew the ends of the elastic piece together to form a loop. Match the markings from the waist of the wrong side of the bikini bottom with those on the elastic and pin them together.
Sew the elastic to the fabric using a zigzag stitch. Fold over the waistband to hide the elastic and sew this flap down using top stitching.
Match the notches on the front and back of the crotch and sew these pieces together. Repeat Steps 4 and 5 for each leg opening to finish your custom bikini bottom.
