NOW TO PUT IT ALL TOGETHER
First I went for the graveyard look, though I tried laying them on their side and clamping them it didn't work out very well. The clamps were too short and I had to rig two together to squeeze one side, so I could only do one at a time, I found the weight of the blocks was enough. Plus I couldn't work on the patio where it is level because then I would have had to carry these down to the lawn...way too heavy for that. I left these overnight to dry and they held very well.
Then I went for the modern art look, the graveyard was scaring the kids. I got in a hurry and only let them sit a few hours,The liquid nails did say it would set up in 20 minutes...it didn't hold. But this turned out to be good, if I wanted to move these it would be hard to do and having two L shapes that rested together on the ground very nicely worked.
