My solution: add some ruffles! I had just purchased a few yards of light blue baby-whale corduroy from Joann's red tag wall. I used about 1/4 yard of it to form the longer ruffle, and found some silk georgette that I had ordered months ago to add a bit of spice as the top ruffle.
This was my first experience with silk georgette, so I did some experimenting. I recall reading somewhere that tissue paper was great to use as a tear-away stabilizer, so that's what I did. It made sewing this stuff infinitely easier!
Because the georgette was so slippery, I decided to forego my handy-dandy ruffler foot, and I used the two-lines-of-basting technique to gather it.
Before gathering, however, I finished the edges on my serger with a narrow rolled hem. After a bit of practice and adjustments to my machine (on scraps, of course), my rolled hems came out beautifully!
Once I had gathered them to the correct lengths for the hem of my skirt, I overlocked the two ruffles together at the top. This made it so much easier to attach them to the skirt, as the corduroy gave some body to the ruffles, and I didn't have to worry about the georgette slipping all over the place.
On my ruffles, I made sure to match up seams, so I could then match the ruffle seams to the side seams of the skirt. I pinned, then stitched the ruffles on the underside of the existing skirt hem, using navy thread and a straight stitch.
Voilà, a great new flirty skirt to wear anywhere!
