Hi, everyone! I have been being contacted a lot lately to paint large paintings (36" x 36" or bigger). Painting them is no problem - it is the shipping cost and packaging that is posing the problem. I see some artists ship such sizes for extremely cheap prices or for free? Are you or they just building into the price of their paintings? I got an estimate from UPS and it was near $100 and I still had to find/create the box and package. Any suggestions would be so appreciated. Where you order these size boxes and who you ship with, etc... Thanks in advance.
