I work with a group who loves wood puzzles, and puts them together without looking at the box. We like that extra challenge! Of course the title tells us something, at least for this one. We tend to begin with sorting colors. In this case we end up with a big pile of light blue, and a bit of lots of other bright colors. Anybody who begins putting together light blue gets pretty frustrated. We've done this one several times, and often several work on it at the same time. One of the things I like about it is that once everything else is done, there's still a pile of light blue, including owl whimsies. Fitting those last pieces in is amusing, because some fit in more than one place, but if you don't get them in exactly the right place, you can have an extra piece left over. Then you have to take a few out and try again. This is a fairly easy puzzle, very satisfying to put together, a charming image when you're done, and fun the second and third time too.
