Isabel belongs to the Raven clan and was taught how to weave by her grandmother, Selena Peratrovich, back in the mid 1960's. Her mother, Primrose Adams, is also noted for her weaving. Isabel uses spruce root, natural grasses, and maiden hair fern to create woven hats and baskets. She is well known for her impeccable spruce root hats. In 2001, Isabel was a finalist for the Saidye Bronfman Award for Excellence in the Crafts. In 2009, she won the British Columbia Creative Achievement Award for Aboriginal Art. Isabel has been included in many significant exhibitions including 'Topographies' at the Vancouver Art Gallery (1996) and 'Native Visions' at the Seattle Art Museum (2002).
