I wanted a weathered and worn look for my picnic table, and since the UV for it would be pretty easy being mostly right angles and such I decided to use an image texture:

I offset and skewed some of the boards, since this is a pretty old table, and also gave one a little bit of warping on one end:

I made the pail with a cylinder and a Bézier curve and gave it a few dents to give it some character. I also tweaked the jars to give them more interesting shape and diversity.

Glass shader for the jars. I used the galvanized steel material from @theluthier ‘s “Realistic Industrial Environments” course for the pail. I’ll finish it all off with some dirt and grime later:
