A few weeks ago I had an idea and wanted to sketch a women's shirt design. When I do sketches like this I use a flat pattern spec template and place it behind some copy paper to draw my design to scale. Sadly, all I had that day was my sketchpad and it's paper was too thick to use this method.
Instead of doing a "woe is me", I just decided to make a notebook using scrap paper in the office.
So I grabbed some scrap paper and got to work.
