And I was reassured I didn't need to buy these write away, (says the unemployed person.) So I said to myself, "Man, I'll make me some stack trays!" I grab some Avon boxes from my mother and grab other things around the house to help me construct.
Before
Here I have push pins, scissor, tape measure, paperclips, tape, and of course, boxes.
After!
The push pins and tape is to keep the shelves sturdy and strong. Although paper items can only be used for light weight purposes.

Only one side the shelves had a flap. I took a paperclip and stuck it through the flaps in a U shape and twisted the ends together. I wish both sides of the shelves had flaps; the paperclip was very sturdy!
