As the pattern for this skirt says, there are a lot of ways to finish the skirt. You can finish the edges with a serger, bias tape, hems, whatever. I chose to serge the edges. This is a four thread overlock with the stitches close together like a rolled hem but the width is still the full width of a four thread overlock. It gives a look like bias tape and I like it. That said, I'm a total newbie to my serger so others can probably give better advice on this part.

Here are my finished edges





I've also topstitched the spiral seams to make the skirt hang nicely





The last step is to attach the elastic waist, once again, there are plenty of ways to do this and most everyone has done an elastic waistband at some point so I won't go into any detail here but I'll show a pic of the finished skirt to end this little sew along, hope it helped someone at least a little bit
