I bought this for my oldest when he was 5, and while he initially needed help to make the planes, as he grew, so did his ability to follow the instructions himself. He made plane after plane, filling my house with pointy little torpedoes. Eventually he memorized his favourite ones and could make them with his eyes closed. His little brother soon followed suit, and the book had page after page turned daily until it completely fell apart. I was thrilled to see that they still make it, exactly as it was 9 years ago when I first bought it.
best paper airplane book I've ever seen.
The instructions are visible diagrams, the pages easy to turn and keep open flat on the floor while folding your plane. The book is nice and large so you can very easily see the little folds in the pictures. Plenty of paper is included for your first planes, but it will run out quickly, because your kids will be addicted to making planes. I siggest buying them their own pack of printer paper so they're not stealing yours.
