Sewing instructions
General steps to sew this garment. Seam allowance is 1 cm (3/8") unless stated otherwise.
Supplies
- Four-way stretch fabric
- Bra band elastic
- Matching thread and the right needle
- Print the pattern at 100%, check the test square and cut the pieces following the cutting list. Transfer notches, darts and button marks.
- Cut with the greatest stretch running horizontally (around the body). Use pattern weights instead of pins so the knit does not distort.
- Sew knits with a serger or a stretch stitch (narrow zigzag) and a ballpoint needle.
- Line the body with the same fabric for extra support.
- Sew the side seams right sides together and press open or finish the allowances.
- Make the straps (turned fabric tubes), adjust the length during a try-on and sew them in place.
- Sew swim elastic to the wrong side of the neckline, armholes and leg openings with slight stretch; fold it over and zigzag.
