I used the same pattern for the underskirt, McCalls 3674. It's really a fairly simple skirt to put together. The trickiest thing, in my opinion, was inserting the zipper since I prefer invisible zippers. I spent two hours cutting out pieces, another hour to sew the skirt panels together and insert the zipper, and then spent a little more time adding the waistband and finally hemming it after it hung for a little while to let it stretch out. No progress pictures because I was lazy, and there's really not much too it.
