The cunning folk
Alongside the trials, and largely untouched by them, ran an everyday trade in practical magic. Cunning folk found stolen goods, identified thieves, lifted suspected curses, sold charms against illness in livestock, and told fortunes. They advertised, charged, and were consulted by respectable people.
The legal distinction that protected them was one of intent and reputation: they were understood locally as working against harmful magic rather than performing it. That understanding was fragile and occasionally failed, but it held often enough that many practised openly for decades.
Their working material was strikingly literate. Surviving cunning folk's notebooks borrow freely from printed almanacs, astrological handbooks and cheap editions of medieval grimoires, which complicates any picture of an oral peasant tradition passed intact through the centuries.
The trade persisted well into the nineteenth century, and in some rural areas into the twentieth, fading with the arrival of accessible medicine, insurance and police.
