I recently made the Lazy Days Skirt with the reverse hem facing. Liesl has an amazing tutorial on how to do hem facings, but when I tried to reverse it so the facing showed from the front, I got a little confused. When I figured it out, I wrote this little tutorial with photos based on Liesl's tutorial on hem facings, but reversed so the skirt is finished with the contrasting fabric trim.
