I'm making some deli cup lids.  I have the ones with cloth covering the little holes.  I want to cut a perfect circle in the center so I can put a foam stopper in the middle.  What tool do people use to make those perfect circle holes as you see when you order the cups with the foam stopper?  I can provide a photo if needed.  Thanks!

Use a bottle lid or something circular to trace a circle where you want it. Then use a pocketknife or other small knife to cut the hole. 

As foam will adapt to the shape of the hole, it's ok if its not perfectly circular.
