I had available a large number of stones that had been used for a walkway, and I cemented four into stands. They look pretty decent.
I am interested, have you got some pictures of them?
Here is probably the best one. There were two major problems - I had to work with the available rocks, and I knew nothing about masonry. One of the others is pretty ugly and I'll be taking it apart, I think, if I can figure out how to break the cement binding. I also have more rocks now.
The plant on it is an azalea I dug up out of the yard a couple of hours ago. It has been there not doing well for about 15 years, along with three others. They are all coming out. I have plans to stick them in some large pots like this one, put them on the back porch in semishade, and see if any are worth doing anything with or if their destiny is land fill. Most of the large branches on it were dead; we'll see what the flowering season does.
