Sewing instructions
General steps to sew this garment. Seam allowance is 1 cm (3/8") unless stated otherwise.
Supplies
- Knit fabric (jersey, interlock or similar)
- Matching thread and the right needle
- Prewash and press your fabric before cutting so it will not shrink after sewing.
- 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.
- Join front and back at the shoulders, right sides together. You can stabilize the seam with clear elastic or a strip of selvage.
- Sew the side seams right sides together and press open or finish the allowances.
- Prepare the knit bindings: fold in half, sew to the edge with slight stretch, turn them to the inside and topstitch from the right side.
- Fold up the hems (sleeves and body) and stitch with a twin needle or zigzag so they keep their stretch.
