landscape edging ideas needed
I want to replace the wood edging as seen in the picture, which is 9" high, but I can't find anything that seems to work for that space. The only plausable option are bricks,they would need to be 3 bricks tall, and my concern is they wouldn't be stable unless i use mortar, which I really don't want to do.
So I have 2 quesetions
1) Can I dry stack bricks 3 tall?
2) Is there a better idea?
Here is a picture and I look forward to your feedback!
