A good way to get ideas out quickly is to start with a series of thumbnails. This helps to focus the attention on major shapes and less about minor details at this point. A design almost always suffers when the major shapes aren’t established first. Focus on an interesting silhouette. A successful design will always have a silhouette that reads well. Usually, this means that there’s a certain flow to the design and it doesn’t feel too rigid. The shapes and the relationship between the shapes will determine whether the design works or not.
