Your stockings are beautiful! Everything is so well coordinated right down to the floss you used to stitch the edges of the hanging loop. I love that satiny interior and the way you finished the underside of the cuff is so nicely done! We have some knit stockings I picked up from Target a few years ago and the underside of the cuff is a stringy unfinished mess.
I was going to say yours look professionally made, but they actually look much better than that! Professionally made = mass produced without care. Yours were clearly done with love, care, and attention to the details.
