I bought 8 mm plywood for 1.5x1.5 m (based on the assembly it is better to buy 10 mm), then placed blanks on the plywood sheets and sawed them out with a jigsaw. Then I bought a self-adhesive film of different colors, having previously decided on the color scheme, hinges, handles, screws and mounting corners.
And transgressed to the assembly. Thanks to my wife for believing in me, because without the Russian mat assembly was difficult
And this is what came of it.
If anyone needs drawings I can send them by e-mail
