Paddling Pool

The tile names cloth the main resource, and for once it is right about the effort. A hundred cloth is a long hemp walk on day one, though a group with a farm running has it in a box by day two. No workbench is involved and every player knows the recipe, so you craft it from your inventory standing in the yard.

The single tarp is the decision. It cannot be crafted, and the small planter box wants exactly one too, also with no research and no bench. A planter turns that tarp into cloth for the rest of the wipe; a pool turns it into an afternoon. Unfolded, the calculator doubles the cloth to put a price on the tarp, but no bench makes tarps out of it.

If tarps pile up later and the base has a walled yard, the above ground pool is the big version, with more tarps and a workbench.
