[General question] Mom and pop fabric/craft stores in y Sewing Machines Parts and Sales in Los Angeles

My husband and I are vacationing soon in the South East area of the US and I’d love to break up the driving with pit stops. His thing is comic book shops and I’m crafty. I’m looking for under the radar fabric stores, museums with good fashion displays, and the like. Anyone know of good places you won’t find online? 🙂
