My baby kenyans look like they need to shed.

I have a bunch of them small gladware containers.

Not sure how to make the whole.

If I use scissors it may look crappy and there could be some jagged edges.

I was thinking of finding something metal and round and heating it up and melting a perfect circle.

Any suggestions?

Also, once finished all I would need to do is place some wet paper towels in there. Correct?

Thanks a bunch.
