Query: Flimsy Pieces

The patterns are great in this book, but the puzzle shape pieces are made of lightweight cardstock; not very durable or easy to use for children. We ended up "laminating" our pieces with clear packing tape to make them last longer and prevent bending, tearing, etc. Next time I purchase a book like this, I will look for one with plastic or wooden pieces.
