I have a good set up for hanging small quilts for photography. It’s a rolling clothing rack (about $12 at Walmart) and yards of stiff poly fleece (this is not the soft jacket style fleece) draped over it and 2 chunks of rigid foam insulation (my favorite building material!).
There is very little distortion to the quilt (it would be better on a flat wall, I know this, but I don’t have the space) making it a good compromise.
I was surprised that the whole lap sized quilt was able to be suspended by just the fleece, so the pins really just perform the task of keeping it straight and keeping it from falling off while I am trying to take the picture.
