Place the front and back trousers together with the right sides facing. Pin and sew from the waist down the side seam to the first large dot. Make sure to reverse your stitching at the dot.
Pin and sew from the top of the pocket bag around the pocket to the large dot, pivot and sew down the rest of the side seam. Neaten the seam allowance.
Press the side seam with the pockets lying forwards to the front.
You can sew a bar of small zig-zag stitches at the bottom of the pocket opening to reinforce the seam.
