Sally Jupiter Costume (Silk Spectre I) from Watchmen

Step 8 Wristlet.

Sew all the way around, leaving a small gap on one of the long sides, trim the interfacing around your stitching, and flip right-side-out through the small gap.  Push corners out from the inside with a dull-pointed object as before.  Press wristlet and whipstitch or topstitch the gap closed.  You can choose to poke holes and insert your eyelets now, since it is pressed.  If you choose to do so, you can also cut your lacing to size.  You need enough lacing to go through all four eyelets and then tie into a bow.
