I threw away more than I used, can that really be right? I'm toying with another way of doing them. By the way, I had similar thoughts about the blocks joining, but perhaps she is being really clever and trailing misleading pieces, like a good jigsaw ?? On the other hand, her finished picture does not match the instructions, so perhaps not. The one shown was a 'test block'. So why not put a picture of one done the proper way? How do you spell 'Aagh'? is that right?
