This is a structural sculpture of how my cards are going to be built up, here you can see that at the base of the card, is a thick piece of card which provides the stable shape and the durability needed to stop the cards bending or tearing. Above this is the texture layer, this is the section where all of my different textures and materials will be, above this there is the photo layer, this will hold my design, the sections that will be textured will be cut out of this layer so you can feel through but not reach the edge of the material underneath to prevent the card being pulled apart. The top and final layer in this build is the sticky back plastic, this gives my card a protective layer which also provides the wipeable surface, the sections that are textured will also be cut out from this layer so you can feel through past it.
This structure gives my card the strength and finish it will need.
The next thing I experimented with is the way the spine of the card will work, what I have done is stick a slightly longer than the length of the card layer over the back of the card while it was folded, this gave me the chance to fold this around the depth of the card, effectively creating a spine like a book. this was then stuck down but not all the way to the edge so that when the card is opened the backing can move away from the card letting it open and close with ease. Here is my sample spine card.
Now that I am happy with the structure and spine of the cards I can continue to develop my designs. I have decided that to give myself the best possible area for my scene inside the cards I will make my cards 7in x 7in making them 7in x 14in when opened, this also keeps me in the large letter size which will keep the cost of postage down. This size is perfect for my cards as I do not want them to be too big for the child receiving them to play with.
