Here is how to make a cool Banister for your world!

1. Choose a material which has a block, a stair and a slab of it.
I chose quartz.
The corners are blocks and it should look like this.

2. After filling it up, put slabs over all the block and stairs like this.

3. If done, it should look like this.
(Note that the center is just my added feature and you can make the banister in any size and any shape and be CREATIVE ;). )
