Step 8: Bloomers
Sew two of the 4 pieces together like the picture shows. This will be the upper part of the pants. Do the same to the other 2 pieces.
Iron the top edges, leaving enough room to pull elastic through.
With both pieces facing inside-out, sew the sides together.
Turn the pants sideways; iron the bottoms of the legs, and sew lace on the outside edge.
Now turn the pants back to the normal position, and sew the inner parts of the legs.
Using a safety pin, pull elastic through the folded top edge. Pull to make it snug, and sew the elastic ends together.
