Designing the initial pages

We are going to have 4 pages at the beginning of the notebook that uses a 3D object to represent each of the four colour books. Each 3D shape will have all of the basics colours from the colour book on the exterior............

We have considered the stock that these designs will be printed on and think that if we use a different stock to the rest of the book then it will draw attention to them and make them stand out. Potential stocks are a translucent paper or and high gsm embossed paper to create a texture.
