You can make chairs out of them! Position them around a fire pit. I did something similar. We cut down some half dead trees them left them in the ground and nailed a long board over a pair to make a bench. I cant tell how tall they are, but if you slice down some seat area and leave 1/4 over for a protruding back rest, even better. Get some inexpensive seat cushions to toss on top/

I've moved house many times and generally leave something - usually I include some instructions eg for the airconditioning or heating units or for the sprinkler system. Also mostly a bottle of bubbly to welcome them to their new house. But my mum did the best, she lived in a house around the time when Australia moved to dollars/cents currency and she collected some "old" notes for each of her children and hid them. About 2 years after she'd sold and moved on she remembered .... but by then the house had been renovated, I hope the builders found and enjoyed the bounty!

Marble benchtop. Classic. Then the window because I have one in the same spot, it's not overly common

The pic is taken so there's only a peek at the artwork- but if I was in that room it is that huge modern striking print that catches all attention, no doubt. And not in a good way.
