Quick trick to making Harley leggings.
Aquire two leggings or pantyhose of separate colours. Snip down the center seam between the right and left legs and resew the opposite colour piece using a zig zag stitch. The zig zag stitch will help keep the stretch. Then you are ready to wear. You can make two pairs with this method, which is great for when you get a run in your stockings
