Brain Tanned Medicine Pouches: Brain tanning is an old traditional tanning technique used by our ancestors all over the world. Every animal has the chemicals in their brain to tan their own hide. Brain tanning involves a huge amount of time, labour and patience generally requiring a 40 hour week worth of labour to tan a deer hide. Over the past couple of years we have traded for a few brain tanned deer (we have no hides available for sale) and made up these pouches. They are all one of a kind, hand stitched, with a bear claw closure/button measuring approx 3″ by 3″ with a deer lacing. The colour difference is determined by the length of time that the leather has been smoked in the curing process. The white is virtually no smoking and the brown is lots of smoke and does smell of smoked hide.
