Cut out all the pattern pieces. Cut one length of elastic for the waistband as follows:
Fold leggings in half Right Sides together, pin and sew with zig-zag stitch along the inside leg seam. Finish the seam allowance with an overlocker or zig-zag stitch.Repeat for both legs.
Pin the elastic evenly around the waist of the leggings. Lay 1.5cm of the leggings waist onto the elastic leaving some of the elastic sticking out. Stitch all around with zig-zag stitch.
Now fold the elastic to the inside of the garment, then roll down again. Pin in place and zig-zag approx. 2cm down from the top of the waistband to secure.
