What the best way and right equipment to make flower arrangement delivery in station wagon?

I need to make a flowers arrangements delivery in a station wagon car from the store to customers’ home, 4 - 5 at the time.


Some times containers have a square or round shape, glass or porcelain.

When I was still in the business we had a wooden frame with heavy rubber tubing nailed into a grid patter. This will hold the odd shapes and keep them in place. Good Luckloan
