A log is /worth $.4. A log makes 4 planks, each worth $.1. There are four items that are improperly priced, based on the number of planks required to construct them.

A Ladder requires 7 sticks (3.5 planks) to construct. Each ladder is currently priced at $.15, $.175 is a more accurate price. I recommend ladders /sell for $.17 or $.18 each.

A bowl requires 3 planks to make 4 (3/4 planks each). Each bowl should /sell for $.075, but $.07 or $.08 is more reasonable.

A workbench requires 4 planks. Each workbench should sell for $.4

A sign requires 6 planks and 1 stick (6 1/2 planks). Each sign should sell for $.65
