As a novice folder, I need as much leeway as I can get. The paper in this set is thin and flexible enough that each fold isn't "set in stone" so to speak, so even if I make a mistake, I can unpack and try again.
The patterns are varied and attractive, though occasionally they seem a bit too busy for some models. On the whole, though, they look rather nice.
Some of the later models I'm encountering in my book seem to require thicker, less flexible paper, however. I can make them with this paper, but it doesn't seem to have the required rigidity for oblong boxes, houses and pianos.
