I have had this happen also.I use X-O odor neutralizer it's a concentrate you mix with water and you can also wash your clothes with it. I will mist (not saturate) my fabric and let it air dry this has helped me with the smoke smell very well. I use a lot of layer cakes or charm pack so you can't wash till quilt is done. I purchased mine from QVC.but I've seem it at Wal-mart and Lowes here in Louisiana.
