It's an ancient craft borne of necessity and repleat with spirtual meaning. It's brain tanning, a craft Native Americans used to make the buckskin needed for clothes and moccasins. But it's a dying craft, with only a few remaining practitioners. Mainstreet Radios Bob Reha met a Fargo woman who is keeping the tradition alive. Sheila Sears Degrewshleler's interest in hide tanning began 12 years ago. She was talking to the curator of a local museum about repairing her daughters moccasins.
