This was the first time I had tried a 3D project and thought it was easy and fun to do. The download comes with instructions, a picture of the finished project and several pages containing the pieces to cut out. The instructions were clear and easy to follow. Once the pieces were cut out it whale came together fairly quickly. The only difficult part was the very small piece near the tail, just because of the size. I would recommend seeing how each piece folds to its connection section before putting adhesive on the tabs. This allows you to see how the shape comes together.
