Bases are an integral part of an origami model; you can't start or initiate a design without creating a proper base for any particular structure. Crease and folding are the secondary elements that contribute to a perfect origami model, but without a good base, your folds cannot be altered into the desired shapes. Pattern Base is one among those fundamental bases in origami which is somewhat similar to a pinwheel/windmill base. It is a simple and prominent base where all the four edges of the paper are folded and inflated to give a bouncy look to the model.
Following is the link to an elaborate and step by step procedure to create a perfectly bounced up pattern base for your origami structures.
