@mismi,
We always made our own soap, which was always great fun.
We made it from fat and lye. It works wonders on white fabric.
The fat, we got from my uncle. He always had plenty.
The lye we leeched ourselves.
My dad, he called himself the lye-er. Always told us what a great job we were doing.
First we dug a pit, to retain the ashes.
Into this ash hole, we'd pack logs. Nice and tight. Then we'd light that ash hole on fire. Even after the fire burned down, that ash would be hot. Hot, white ash. We'd have to let it cool, then we'd dig it out.
We'd leech the lye from that white ash, and mix it with the fat. Then we could get cleaned up. Digging in that ash hole always made me filthy.
