Everything needs to have a place: box, drawer, hook, anything. If it doesn’t have a place, it’s just going to end up randomly anywhere and everywhere.

You need to decide a fixed place for everything. There needs to be a fixed place for yarns, maybe multiple places for different types of yarn. There should be a specific location for fabrics. If there’s not enough floor space, start using the walls. Even the ceiling is a place where you can attach hooks, loops and whatnot.

You just need to make a hundred little decisions while organizing everything, but once that’s done you can skip the burdensome decisions in the future and simply follow the system you built earlier. Once there’s a system, don’t deviate from it, and that requires some discipline. If following it becomes a routine, you no longer have to spend much mental energy in sustaining it.
