I hope it’s okay if I share about my early exposure to Lakota jewelry. In the 1980s I was fortunate enough to meet and honor an acclaimed artist who received a national award for her preservation of porcupine quill and bead artistry, Alice New Holy Blue Legs. Still the coolest name I’ve ever heard, and I’ve long wondered if the Holy of her name connects to the Holy Bear folks. I had a medallion necklace and quill earrings by her for many, many years. Porcupine quill is actually pretty fragile, and after years they broke. I might have one of those earrings loitering around somewhere. The medallion was composed of flattened, dyed porcupine quill such that it resembled basketry in a way.
Here’s Alice:
