Selecting the required materials
This step was hard to solve, because the materials must be light, sturdy and cheap.
The woman thought about the plastic cutting boards.
She walked a lot of stores checking out every perceivable option, but it looked like cutting boards were her best option.
She bought a large one from Sam’s Club on clearance for only $5.00 and two from Walmart (15″ X 20″ – no handle cut out).
The woman cut them in half and this gave her 10″ X 15″ pieces.
So, she had the 4 dividers she needed and would modify the length to the size needed.
