It just doesn't get any easier.
Here are the tools: Scissors, small jar, biscuit/cookie cutter, kombucha SCOBY.
I took the large SCOBY from my crock. It had formed several layers, so I separated about a quarter inch layer off of the whole, replacing the whole into the kombucha crock and keeping the thinner layer to make 'babies'.
Using the biscuit cutter, I made an indention in the SCOBY. I used the indention as a guideline for cutting with the scissors. The SCOBY was large enough to allow me to make several of the 'baby' circles, as the one above. (It's the jelly-fish looking thing beside the biscuit cutter.)
Put the 'baby' SCOBY in the clean jar.
