When lacking a large enough wall space to hang a finished quilt for pictures, I think it's OK to take pictures of the quilt on whatever surface is available, as it will only be for a short period of time, then the quilt will be removed. I did, however, get upset when I saw a picture of a family reunion quilt that I'd made, lying on the floor with my nephew and his very large Labrador dog. Apparently, the quilts mean more to me than it did to him, but there's nothing I can do about it. I make them for our bi-annual family reunions with the intent that they be passed on to other generations, but perhaps they mean more to me than they do to some of my family members.
