Sewing instructions
General steps to sew this garment. Seam allowance is 1 cm (3/8") unless stated otherwise.
Supplies
- Woven fabric (cotton, linen, poplin…)
- Lining fabric
- Zipper
- 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.
- Sew the princess seams matching the notches; clip the curves before pressing.
- Make the straps (turned fabric tubes), adjust the length during a try-on and sew them in place.
- Sew the side seams right sides together and press open or finish the allowances.
- Assemble the lining like the shell, attach it to the facings and bag it at the hem, leaving an opening to turn.
- Insert the invisible zipper in the back or side seam and close the rest of the seam.
- Hem: double-fold to the inside, press and topstitch or blind stitch.
