When taking a road trip, these are on my list:
The Back Porch in Pacific Grove: my absolute favorite
Betty's in both San Luis Obispo (SLO) and Santa Maria: next favorites
Roxanne's in Carpenteria
Sew Fun in Atascadero
Stone Mountain and Daughter Fabrics in Berkeley
New Pieces Quilt Store in Berkeley
Candy's Quiltworks in Northridge
Thimble Towne in Visalia
Are you taking the coast route (Hwy 101) or inland (Hwy 99)? It's roughly 8hr + side trips.
Do you like totally traditional? Sweet/cute? Modern? Contempory? Art? Batik?
