Jacob tells us in Jacob 4:1-2 that the plates were difficult to write on. But they would preserve the knowledge of his people for their posterity far better than any other means.
I took a cereal box and cut it up into rectangles that would fit into their journals. Then covered them in heavy duty foil.
Each person was to take a toothpick and write their testimony or
something they learned from the lesson on their plates.
Then they glued them into their journals.
