First, I measured the waist and length of the little girl. I then cut material to five times the waist measurement (plus seam allowance) and exact length (plus seam allowance). Then, I folded the material in half width wise and pinned it together to be sewn along the width of the fabric only.
Turned it inside out.
I then sewed six channels 3/4" apart across the width of the skirt and inserted 1/2" elastic (measured to the waist of the girl plus 2") into every other channel starting with the second channel.
Once the elastic was inserted and sewn down the side, I folded the fabric in half and used a french seam to sew together and finish the skirt. You can see it being worn below. Super cute, right? I think it would make a super darling skirt to just wear around.
