My cake boards are about 1/8" (or less) bigger than my cakes. Both boards and cake pans are Wilton. My question is how to trim them up to not show (I am doing a wedding cake with fondant and ribbon...otherwise I would just use a buttercreme boarder), without the edges being all jagged. Any simple sugestions?? Oh yea..did I mention the cakes are already on them?! : ) Thank you!!

Wow that's a tough one. Are the cakes already iced? If not, then I would just ice out to the edge of the board. If they are, the maybe an exacto knife? Just for future reference, I use 1/4 foam board under my cakes. It makes it much sturdier to move the cakes, stack the cakes and unstack the cakes. Good luck! You may just have to do a simple border. I would just match it to the color of your ribbon.
