I was grateful for Karen Margulis’ blog and her ideas for posting (shipping) pastel paintings. So far I’ve sent several small pastels from England to America and they’ve all arrived safely. I use glassine paper to protect the pastel surface (for those of us in England, Jacksons Art in London sells this). I had difficulty finding suitable foamboard locally, so decided to cut up some hardboard and make two rigid panels to sandwich the pastel between (with a small overlap all round). These are then firmly taped so that they don’t move. My local post office sells a good supply of lightly padded mailing-bags, and in various sizes, so that (so far) I’ve had no difficulty mailing off a 9x9 inch panel sandwich. Admittedly hardboard panels are a bit heavier than foamboard, but they seem to travel overseas just fine.
