What do you use to cut a perfect hole?

[lectricblueyes]

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.

That's exactly what we did.  But doing that 50+ times...  Im imaging a jumbo sized hole puncher lol

I use one of those for small nymph cups, then paper over them (shippers) or organza mesh (keepers)..

If you are a member of Mantis Keepers in FB, this is what I do for nymph cups:

I just made these 4 oz cups for L1/L2 nymphs.  We took pretty similar paths.  Thank you.
