It will look like this when cut
Here I cut a piece for the back which is just a triangle. Lay the stocking on top with right side facing in. Sew all the way around starting at the top but leave the top cuff open to turn right side out.
Leave top open just sew around the outside.... turn
cut out lining ( I used muslin )
leave a space open in the toe for turning .... sew toe close after turning.
I sewed an extra stitch around the top of the cuff.
