These paving stones are not as tall or tidy or heavy or sturdy, but they let me make raised beds 8", 12" or 16" deep almost as fast as I can wheelbarrow the soil into piles.
They don't have to lean every-which-way, I just never mortared them together and haven't straightened them up in a year or two.
They're probably also cheaper, at 71 cents to $1.80 per linear foot.
