I couldn't imagine quilting without my cat. When we used to live in NJ and I sold something at a fair, it was required (at that time) to put the fiber content on the item. For instance a quilt might read "100% cotton fabric, polyester and cotton thread, 100% cotton batting" mine would read "100% cotton fabric... 99.9% cotton batting and .1% cat hair". Seriously I wash anything when it is done. If it is mine, I put it where it belongs, if it is to leave the house I wrap it in a clean sheet (or pillowcase) so it stays that way.
Another note - I used to use a ton of lint rollers until my daughter suggested I use rubber kitchen gloves (you know the kind you get at the grocery store). I put those on and rub the quilt and the hair comes off I think better than the lint rollers!
