About this craft

One rope is the only line on this bill you can't pick up on the way home. The calculator unfolds it into cloth, but no bench turns cloth into rope, so every coil comes out of a road barrel, a crate or a recycled bow. Satchels and bows want the same coils, and an alarm usually comes last in that line.

The bigger cost arrives after the craft. Rigged with a beancan grenade, the alarm turns into a trap, yet the calculator leaves that grenade out. Count its sulfur into every rigged alarm and keep plain ones for spots where hearing someone is enough.

The recycler gives the rope back only some of the time, so a spare alarm returns mostly wood.
