When we decorate in our interior, we will use various wood moldings, such as coated covering wall skirting board, Quarter Round Baseboard Trim and round baseboard toe molding are installed at the bottom of the wall, and the position of the ceiling is decorated with contemporary wood sanding crown molding. These decorations Will make the room design more elegant   In the actual decoration, the more troublesome thing is the connection between the mouldings. How to make the gaps invisible or very small? Under normal circumstances, we calculate the size, adjust the angle, use a saw to cut, and glue to connect, but sometimes the splicing effect is not very beautiful.   One particular type of moulding is tongue and groove moulding. One side of the moulding has a groove crafted into it, and the other moulding piece is crafted to include a small protruding piece that is called the tongue.
