Skirt With Scallopy Hem

My latest finished object is a circle-ish skirt (it's 2/3 of a circle, so I'm not sure what to call it).
It's made from vintage fabric that I had in my stash.
I wanted to put some trim on the bottom to dress it up as well as to help turn the hem. After looking through my notions box and playing around for a while, I ended up taking bias tape and running it through my sewing machine using the shell- stitch setting (the one that's used for blind hems). I then machine sewed it to the skirt, turned the hem and then hand sewed the other half of the bias tape to the skirt to hide the raw edges.
