he original design, copied and pasted it. Then I dropped the second block down, halfway, beside the original block. This is a half drop. When you do this repeatedly, you can get a repeat pattern.
Here I have reduced the original again, flipped it horizontally and pasted it as a block repeat.
You can use this flip horizontal as a half drop also.
As you can see, there are many permutations that you can play around with. One easy difference is the brick repeat, which is like the half drop but done in a horizontal orientation rather than the vertical that I have used in the above examples.I hope this helps.
