I started off making the 7 rd boxes inside.....your big box will hold 6 of those boxes.
These are your measurements. The Craft Paper Tape can be had on Ebay or Amazon.
(Make sure it's water-activated and not re-enforced.)
The cardboard is chipboard backs to office calendars.
I used an orange typing paper from Staples at the time,...It probably could use to be a little darker orange.
This 50 Spencer box is the wrong tape, this was just a proof of concept .
