Place your pots upside down on the top of your container lid. Now trace around each pot with a pencil making sure that no lines overlap.

Now, if you have a compass, set it to the radius of the BASE of your pot. Eyeball the center of each circle (or measure if you prefer) and trace another circle inside the larger ones.

Next, cut away the SMALL circle and cut perpendicular relief cuts up towards the larger circle (see picture for clarification). The idea is to push the pot down into the hole and the container lid will hold on tight making a better seal.

What is the easiest way to cut the Styrene lids? I have a carpet knife but it feels pretty dangerous--is the an easier way to cut this stiff plastic?? Also, why does the box need to be so deep? I am using an "under the bed" style of box about 6 inches deep. Should I expect trouble?

Yo, hole saws work really well for making nice circular cuts in ANYTHING. Trouble is finding the sizing to match up with net cups as different brands actually have a different "lip" on them. Thus, a 2" hole saw might work for a 2" net cup and it might not depending on the mfgr. Helps to be able to measure for yourself. There are also "adjustable" hole saws that use a toothed blade that has an adjustable circumference from the drill bit part. They don't usually work the greatest, but it will be accurate.

You don't really need to make those tabs since you pots have a lip, just cut the hole big enough to hold the pot (the diameter under the lip), but smaller than the lip (the first circle you traced), the pots will drop all the way down level with the lid.
