I am one of those dreaded smokers. And I have 2 dogs that are allowed anywhere in the house. I don't sell anything. When I give quilts as gifts they all washed, sprayed w/Fabreeze (sp) and packaged before they are gifted. And all recipients know the circumstances of my life/house. When I do blocks for swaps (rarely for the above reasons) they are Fabreezed first and sent in a plastic ziplock. I always include a note stating the pet/smoke with apologies and if the block can't be used for those reasons I understand. Haven't had any adverse comments yet.
