Although I have not taken time to look at this particular set, most of the chipco stackes are easy to put together if one lines up the chips by the number on the sides of the chip, such as:
1 of 5,
2 of 5,
3 of 5, etc. in this order, no matter which side is on top. In other words, stacking all the common sides together, might not necessarily work. Any particular stack may have two reverse and 3 obverse in a stack.
