Duplicate Stitch or as its sometimes called "Swiss Darning" is a great way to add a name on your Christmas Stocking or to mend a hole in your knitted sweater or socks. I've searched the web looking for a really good video on this technique and finally found it on the Berrocco website.

I found this technique to be so helpful in mending other people's knitting and when done right, the repair is practically invisible. The video above by Berrocco, is fantastic and I know you"ll love it. Enjoy!!!
