It's that simple:
Transfer the size of the box bottom to the plywood and cut it with a Cutter and a long metal ruler. Now mix light blue and old pink Handicraft paint with Ivory to pastel shades and use them to prime the box and the plywood
After drying, screw the board onto the upside-down box. Tape-Ribbon to the checkered tape so that the screws are covered and decorate the outside of the box with it. Finally, apply the Stenciling ink to the stamp with the snap sponge and press it onto the table top.
