We participate in two studio tours a year:
The last weekend in April is ArtInBloomSeattle.com, a garden art themed tour of about 6 studios/yards with 15 to 20 artists.
The middle of October is GlassAndDecor.com which presents art for the home in about 6 studios with 15 to 20 artists. This is part of the big city-wide glass celebration RefractSeattle.org
