In this tutorial, I'll demonstrate marking the hem on my pink cotehardie, and demonstrat hemming both a lined skirt, the blue cotehardie, and unlined skirt, the pink cotehardie.
When making skirts that will be leveled at the hem, I always make them a little bit too long. You can see that here. The gores in particular are quite long on this one. When I cut them, I didn't take the longer diagonal edge into consideration, knowing that it would be fixed when the dress was hemmed.
If you're sewing by hand, leave the last inch or so unsewn so you don't have to worry about picking out and refinishing seams later.
