To Wash or Not To Wash…

this is the question. And I’m not talking about fabric. I  pre-wash 95% of my fabric. The only time I have not pre-washed is when making One Block Wonder Quilts or Rag Quilts made from pre-cut charm packs.   What I would like to know is, should or should I not, wash a finished quilt that I am selling? Most of the quilts I’ve gifted, I’ve washed before giving them. It makes them all cozy and crinkly.  But should I wash a quilt I’m selling? I’m really interested in what my fellow quilters have to say on this subject. I appreciate any and all comments.

Thank you.
