Has anyone weighed scooped Stirling? I've been scooping 1/4 of a teaspoon to bowl lather. Usually it works great, but sometimes i feel i may have used too little soap. Has anybody weighed a teaspoons worth of Stirling? I don't want to use too much soap, while Stirling isn't expensive, it can cost quite a lot to ship to my country. I don't have a scale that i could use to weigh it
