i you don't want to pre-wash you should launder the finished item. I am a 'sometimes i pre-wash, sometimes i don't ' but i never let a quilt go away regardless of where- it could be a gift, a donation or a sale...it does not matter- as soon as the binding is finished the next step is laundering- i toss them into the washer- cool water, gentle cycle- with detergent then into the dryer- i also ALWAYS add care instructions to the label along with fiber content. doesn't matter if the fabrics are pre-washed or not the finished item is ALWAYS. I want to know everything is ok---colors, seams, embellishments...what ever- i treat it as I believe the new owner will --- especially baby/kid quilts---they need to take alot of laundering & use---they better be able to take it. and i don't want to send anything out the door with chemicals (sizing), oils, grime, markings....
