I Always launder quilts as soon as the binding is done- I consider it the final step to completion. That way I know if anything is going to go wrong. ( a seam unstitched, a color bleed, a loose applique...etc) also removes any oils from my hands, any markings, starch, fusible....the list goes on. I want the new owner to not have to deal with any surprises ( unfortunate situations) after receiving their quilt. I always take plenty of pictures ( whole quilt and detail shots, top and backing) so if someone does damage their quilt I have proof it was not damaged when I sent it off.
