So my outside composter was pretty well broken down, just big clumps of decomposing material mostly..

I decided to throw it all in a new bin and put a bunch of worms into it to further break it down.

Anyone else doing this? Any tips on making this better?

I didn't create a new "flow through" - I just dumped it in a rubber maid and put the lid on - I'm checking it daily for moisture and to mix it up and get oxygen in it...
