I don't do many but I wrap them up in a giant canvas. I don't want anything getting on it. They come back in paper or plastic depending if they are opening right away or storing.
Before picking up, we ask if they're storing or shipping the rug(s).... Most tell us if they're storing or need it wrapped for shipping.... Just pick them up, and do a good visual back at the shop.... If no storing or wrapping for shipping, they just get tied with twine and put in the van...
