First you must take inventory of all items in order to be able to create your bag. Make sure all labels are in the correct order. Lining should be ready before attempting to begin construction. The stay should be 10in long and 4in wide. Pocket the stays and glue the stays to the outside fabric. Use the notches to line everything up. Take the magnetic snap and attach it to the front and back. Take a knife and cut holes for the magnetic snap. The magnetic snap comes with a washer. Use cardboard to help brace the washer for more stability. Apply rubber cement to the top and hold the edge over until it holds firm. Do the same to both pieces and let dry. Make a slit for the magnetic snap and make sure you leave enough room so that you can sew. Apply glue all the way around the bag, then let everything dry. Once everything is dry, you will be ready to sew. Turn your flaps all the way around. Use small strokes in order for the material to fall naturally. Ensure both flaps are the same size and prepare to sew. Ensure you practicing safety procedures while handling sharp objects. Sew the two flaps together starting from one side and gradually moving to the extreme side. Notice the vivid detail in the black and white pattern on the material. Try to match up both sides so that they compliment each other.
