I am planning to use the rectangular 12x4 retaining wall blocks as below
This is because we like the design of this better than using trapezoid shape (not available locally for Tranquil color and special order is too expensive).
Now this block is good for 90 degree edges only. For example:
How do I lay them out in below shape and angle? Without cutting the 4-in concrete?
Or do people leave the gaps in the front wider as it's getting closer to the corner like that?
I am open to any creative idea for that corner. I was thinking about creating a small square-looking seating column using 3x4 of the blocks to "mask" the adjustment in angle and gaps.
