OBW is when repeats of the same unit are put together to form a new pattern similar to a kalaiscope pattern. 6 triangles are put together to form hexagons without any other fabric sewn to them. I don't think you can put yours together into a pattern due to additional fabric added to the edges. The hexagons halves are then sewn together in rows and the rows are sewn together. Cutebuns did a tutorial for QB you might get some pointers from it.
