This is how the travel case is made:
Divide the DIN A3 sheet of rock paper in half. One half becomes the "envelope" of the folder. From the rest of the rock paper, cut the remaining parts of the folder according to the template. The small rectangle becomes the window and the large part becomes the inside pocket.
Glue the envelope with the complete Straw silk paper "Map" using Napkin varnish. To do this, apply it to the envelope with Napkin varnish a brush, place the envelopes on top Straw silk paper and brush them again with Napkin glue.
After drying, fold the envelope in the middle lengthwise.
