I typed in the search box at the top "center knots" and got several previous posts and links.
Here is one listed in another post: http://brooklynsbows.blogspot.com/20...ench-knot.html
Here is one to a page on this site: http://www.hipgirlclips.com/store/in...oducts_id=1544
Hope this helps. Thanks to the others who answered this question for us before!
