I recently rebuilt a 20 year old garden cart I had made over 20 years ago. (the one on there right). Then Mary said she would like a smaller one for carting around her water pails or pails of planting soil. (the one on the left)
Then I decided to make a planting cart for her out recycled shelving, shovel handle, kids bike wheels, hard wood flooring (for legs), shelf brackets, and palette wood.
