Mix oils and lye into bars you'd actually want to use.
There's a chemistry-lab seriousness to it that surprises people: lye is genuinely caustic, you'll work in goggles and gloves, and a miscalculated recipe means a batch that's lye-heavy and useless.
The payoff is tactile and a little smug, unmolding a fresh bar, smelling oils you blended yourself, knowing exactly what's in something you'll lather up with.
The catch is patience, since most soap needs weeks of curing before you can even try it.
Honest tradeoffs before you spend money or clear space.
The essentials run about $239 — you don't need it all to start. Each project lists only what it uses, and the first is often free. Links open Amazon (affiliate tag).
