Posting and packing
One of the most nerve wracking things is shipping work. Will arrive in one piece, will it arrive at all. All you can do is obsessively pack the piece and pray to the shipping Gods that they will arrange for your work to be delivered in one piece and on time.
A good starting point of the packing process is bubble wrap and foam board and a good box.
This is how I ship a smaller work. I will make sure the next time I’m shipping a larger work I’ll take some pics and share those as well as I use a different kind of box.
