Duplicate Stitch

I have never done the duplicate stitch…is there a video out there I can look at online that shows this technique?
Thanks for your help.

I usually prefer watching a video to reading instructions and diagrams when learning a new technique, but I found this site very helpful recently when doing duplicate stitch for the first time:

Just scroll down a little to the section about duplicate stitch.

Its not difficult to learn. Its also called Swiss Darning so you could google that term, too.
