Shipping of Arts

I am selling two of my paintings, hopefully. I've found that I would much rather sell to someone I know, than to a complete stranger. At least I know they are genuinely interested, and I can get updates at to how they are enjoying them or using them. The person interested is looking at Numbers:


And Vulnerability:


It will be interesting trying to ship Vulnerability though. The canvas is 48in x 24in. So either I need to find a large cardboard mirror box, or have someone build me one. Either way it will be time consuming and expensive to ship.
Numbers is a painting that is hard to let go. It means a great deal to me. There is a quiet passion within it. Hopefully the person buying it will be able to see that.
