What is the best way to ship a painting?
 

I am working on 2 commissions that are fairly big and will need to travel half way across the country. Their sizes are 48"x54" and 42"x 46". What is the best kind of packing and box, and what is the best shipping method?
And, a client may come to my town and then take a painting across country with them. In this case, is an airline a possible option?

You'll find some information in this thread:

There's also some art shippers in my Resource & Biz Center.
