Connect the dots, as shown on the diagram. Don’t worry too much about the curves – you just want to make sure that the pointed ends (the 10cm marks on the sides) are at right angles so they match up nicely. Cut out the shape and label it ‘Bloomers – cut 2’. Fold your fabric in half, right sides facing, and cut out two bloomer pieces.

With right sides facing, pin one leg piece and sew the in-seam with a 9mm seam allowance. Finish the raw edges with a zigzag or overlock stitch, then repeat for the other leg piece. Press the seam allowance toward the same side for both legs.

Turn one leg right side out and insert into the other leg that has the wrong side facing out, matching up the curve of the rise. The legs should be facing right sides together. Sew along the curve with a 9mm seam allowance. To reduce bulk, the in seam seam allowance for each leg should be pointing in opposite directions. Finish the raw edges with a zigzag or overlock stitch, then press.

To create the waistband, fold the top edge toward the wrong side by 5mm, and press. Fold another 1.2cm toward the wrong side, and press. Edgestitch, leaving an opening of about 3.8cm at the back centre seam. When folding and pressing to create the waistband casing, you may find that some parts are curved in such a way that makes it trickier to keep the seam allowance the same width throughout and might require a slight stretching of the fabric as you press.

To create the elastic casings for the legs, fold the bottom edge of one leg opening toward the wrong side by 5mm, and press. Fold another 9mm toward the wrong side, and press. Edgestitch, leaving an opening of about 3.8cm on the in-seam side. Repeat for the other leg opening.
