The Maverick Messenger pattern is for experienced leather workers with some experience with wood. It is not a standard sewing pattern and requires hand-stitching the leather. No sewing machine is required.
This pattern is aimed at intermediate bag makers. It is not a comprehensive guide so does require you to have prior knowledge of working with leather and wood.
It's a free pattern produced by Country Cow Designs. It comes as two seperate PDF downloads, one is the guide and the other is the printable pattern. Please do not reproduce this pattern or claim it as your own design, but you are free to sell bags made from this pattern on a home based production basis.
