Adding a side seam to your Blue Jays
Fold your Blue Jays pattern in half to find the centre. The pieces won't match up evenly along the top. This is due to the rise in the back of the shorts.
Add a 1 cm ( 3/8 " ) seam allowance to the front and back side seams.
Cut out 2 x back pieces (mirror image) and 2 x front pieces (mirror image).
Overlock / Serge the front and back centre seams and crotch.
With right sides of the fabric together, sew down the back centre seam, using a 1 cm ( 3/8" ) seam allowance. Repeat with the front pieces.
Press the back seam open.
If you are adding ruffles to the back of the shorts, you will need to do so before you join the side seams.
With the right side of the fabric facing in, sew the front and back shorts pieces together at the side seams.
Join the shorts at the crotch and add the waistband and leg cuffs as per tutorial instructions.
