After removing nails and sawing off rough edges, I had to buy some screws (since I couldn't remember where I'd put the ones I had from a few years back). Once I had screws and tools sorted out, I started by making a few planters. They had to be free-standing and durable enough to take the weight of soil and plants... and not get blown over on windy days. A further complication was the multidirectional sloping of the paving. All the legs had to be cut to different lengths for everything to appear level.
With the last of the wood, I decided to make a personal chair...
Notice the folding drinks table on the arm
The shaped back spars were originally used to keep clay drainage pipes apart when stacked. After doing a sketch to show my friend George, he said it reminded him of an Adirondack chair design. (I'd never heard of them, but a web search brings up loads). Here's another view of the layout:
Amazingly, I ended up with exactly the right amount of wood for the whole project. All I had left at the end was one small bin bag of sawn-off rough bits - which my neighbour said he would take for kindling to light a steam traction engine's boiler.
So... Time to think about the next phase...
I have a cunning plan...
