2

Flesh the Hide

Drape over smooth log, flesh side up. Scrape off ALL fat, meat, membrane with dull blade or bone tool. Every bit must go or brain can't penetrate.

Materials for this step:

Animal brain or 3 egg yolks1 piece

Tools needed:

Fleshing tool (dull blade/bone)
Smooth log
3

Buck & De-hair

Soak in wood ash lye 2-4 days, stir daily. When hair pulls out easily, scrape off all hair plus the grain layer beneath.

Materials for this step:

Rotten wood for smoking1 bundle
4

Brain & Stretch

Mash one brain (or 3 egg yolks) in warm water. Soak hide overnight. Wring on a stick, then stretch continuously as it dries — 2-4 hours of constant work. If any spot dries un-stretched, it goes stiff.

Materials for this step:

Raw hide1 piece
Animal brain or 3 egg yolks1 piece
5

Smoke

Sew into a bag shape, suspend over smudge fire (rotten wood). Smoke 1-2 hours until golden-tan throughout. This makes it washable — unsmoked brain tan reverts to rawhide when wet.

Materials for this step:

Raw hide1 piece
Animal brain or 3 egg yolks1 piece
Rotten wood for smoking1 bundle
