Negatives:
1 / layout: The notebook contains photos of models across a description page, the necessary equipment, and numbers to find the patterns on the boards. Bosses are two large leaves virtually A1 format, black and white. It is not practical to maneuver.
2 / Schemas: For each model, there are two pattern: one representing the colors (patterns, since one is in black and white), and a representative how to spend the son.
I think of the children who often already struggling to follow a pattern. There must follow 2, it is not possible. And without color, it is not pleasant. This is unnecessarily add complexity.
3 / The problem: Many models require passing the wire 3 times in a long row of pearls. With average quality pearls is simply impossible. I had to adapt the model to achieve it, so it was ugly on one side. It is not very inconvenient for a flat model which can not benefit one side anyway, but I do not understand how the author has managed. If the models are accessible to children, I think it is important to check the quality of pearls before.
