I don't usually wash, I like the "wrinkley" look as I like to do traditional designs and I feel like they look older than they are. I only wash the fabric if when I pick it up it feels like it would bleed or is stiff. Gentle cycle cold always. I only usually iron if it's really wrinkley too. I don't have enough time to worry about washing and ironing fabric before cutting. and as most are scrappy, I don't think it really matters much anyway
