What Have I Got Myself Into?

A couple weeks ago I was contacted by a church about a donation they received. I went and looked at it.. made them an offer and they accepted it.

This is what I saw when I looked in the building… a bunch of empty plastic tubs. #2 wanted the tubs to sort out his Legos.

Once we got all the empty tubs out.. we found thousands of patches, appliques, trim and wedding stuff. There is SO much there.. I'm not sure how to list it, where to list it and how to store it.

I've really am not sure what I got myself into.. This is a lot of stuff. Any ideas on how to sort and store it?
