Sorting squares..............

I need to clear the trays of batik colorwash squares off my 2 dining tables in the basement.  I bought 10 more disposable aluminum cookie sheets at a dollar store and then filled them with the overflow from other trays and boxes.
This stack is already done.  I have 53 trays with each having an average of 24 different fabrics on them.  That is at least 1272 different fabrics to choose from.  The stack of trays is too tall to put the lid on the storage box.
 
As I was stacking then and putting then into the storage box I saw one more box...oh no, I thought I was done.  I might as well finish this project today.
