To evaluate my design ideas I am recording them in a development sketchbook. I'm using this method so that I can record scale and placement ideas, technique research and the development of how the idea could be used in a final sample for fashion. These are examples of some of the pages in the sketchbook and I pretty pleased with them. I'm not normally one for lots of annotation but I'm making a conscious effort to record all of my thought process.
