A COPY OF THE ZIGZAG

Any complex shapes are easy to copy, if you use a set of thin plates from the available material — cardboard, plywood, plastic, metal. Enough to push a package to the playable terrain, and a sliding plate just repeat the pattern twice: on the mating surface will be a matrix, “concave” option, on the opposite — the copy, if the plates were strictly the same width. To consolidate the obtained image, holding the bag with a clamp. If the components of the package were pre-lubricated in any non-viscous adhesive, after drying and processing will receive the finished product, just repeating the original drawing.
