It looks like it's stack & whack without the step of lining up the print to get identical cuts. Cool! I think it's interesting that they say "this is what it will look like when you receive it" and show pictures that are 6 X 20 squares, but the purchase buttons say they are 30 X 4 or 30 X 8.

I saw that, too, Donna. I hesitate to purchase b/c of the inconsistencies in the descriptions. I do like the idea behind it, though. Would either be very fun or very frustrating to put together. :)
