How I made my lace-up the back socks:
I tried the socks on and marked the spot I wanted to cut down to and I also measured the socks while they were on me from the bottom to the top edge. I did this because I knew the socks were stretching a bit and the lace trim I was using did not stretch. It ended up being about an inch and a half longer than when the socks were off.
Then pinned on the lace trim to each side stretching the sock evenly to be as long as the trim.
I sewed the trim on using a stretch stitch and slightly pulling the sock as I sewed.
I did take great care to make sure both sides of the trim matched up.
I then used 1/4 inch organza ribbon to lace the two sides back up.
