I am fortunate enough not to have to work, so it is very easy to bring fabric into the house when hubby is away. However, I do wash all my fabric as it comes into the house and sometimes he has added to the laundry and has seen LOTS of fabric, all neatly folded, ready for the wash. I just say nonchalantly, "Why honey, I've had that fabric for years; I'm just getting around to washing it for my next project."
or I might say -
"Every decent quilter worth her weight HAS to have a big stash to reach her full potential and create those beautiful quilts you cover up with while your watching TV!
Hhere is only 'part' of my stash, since you said only ONE picture allowed and unfortunately I don't have a wide angle lens!
Sweet Home, OR
