I really like the inconspicuous casing she adds for gathering a sleeve cuff with elastic. On the show you'll see her use purchased binding. For a super neat finish you could consider cutting you own bias strips of fabric, using Dritz bias tape makers to form the bias strip. this would be especially nice if you want to maintain a soft feel and a clean look inside your top.
I used Razzle™ 6 ply rayon thread, generously provided by Wonderfil® Specialty Threads for my cording, feeding it through a five-hole cording foot. Then I selected a checkerboard stitch to anchor it in place.
