Until I get the Gospel Fly website brought over to these woodworking pages, you can take a look here:

If you as a woodworker have a Christian clientele, there are some ideas on the GFly pages that might give you a few new ideas.  Pens, desk accessories, pendants, etc.   I'm not selling the Fly that's tied on a "real" hook any more.  Too dangerous for little fingers...or big ones for that matter.  (speaking from personal experiences.....don't ask)  ; )
