Step 6: Topstitch serging to tack down. My serger wasn't cooperating today, so my serging is wonky.


Step 7: But elastic ends together and zig zag (or use your machine's darning stitch) to close into a circle.


Step 8: Mark 1/4's and pin elastic to panties' waistband raw edge.


Step 9: Secure elastic onto waist with serger. I usually let the fabric hang over a tad so that the serger has something to cut off -- makes a neater edge IMO.


Step 10: Turn elastic to inside and stitch. Again, I usually use my coverstitcher here.


All done!
