I've seen this font in action. It was so much fun playing with it on a friends computer. She does x stitch with her designs.
I wanted to share the site with you since alot of you like to carve celtic knots. There is a charge for the font but its not a crazy price. If I'm wrong for posting it here.. please delete this post if you wish.
The gallery is fun to go through for ideas on how this font was used in crafts and woodworking and wood burning.
There are tuturials on how to put some of the knots together. And the font works in quite a few programs including Word Pad.
Heres the site.. have fun!
