This work explores the techniques of printing and preparation, in combination with technical mistakes. It aims to show how to use technical mistakes in different printing and preparation techniques as a design method to find accidental aesthetic expressions using the stripe as a tool to enhance and clarify the methods modification. The method confronts today’s textile industry by showing how these mistakes could develop into new expressions within textile design when fast -fashion is no longer an obligation. The stripe is a common shape, and is explored to clarify the method ans show how different techniques can change the stripes in various ways. This resulted in to three pieces each representing a technique; one transfer printed, one digital printed and one with the starting point in screen print. They present examples of how more time for developing mistakes in textile design can lead to development of the common shape of a stripe, broaden the technical limitations, and give a value to mistakes in the textile industry. By taking the method further more mistakes could be developed, and how to produce the developed designs in the industry could be investigated.
