Sources of CFFA Official Dress:

The Texas CFFA has been working closely with Wayne and Sherry Rode of Creative Awards & Trophies in Fredericksburg, Texas. Creative Awards offers navy blue blazers/sports coats to CFFA members at very affordable rates. Sherry and Wayne also create the official dress logos with your institution's name on it. (The logos take approximately three weeks for delivery, so you may want to contact Wayne and Sherry soon!)
