Making big changes in your house can also make big changes in its visual appeal – however, there are a set of guidelines to be followed so as to ensure your tedious efforts do not go in vain. When you want to work on your walls, for example when you want to carve a shelf out of it, you need to observe optimum care. Not only do you have the restriction of the shelf width of 16 inches (owing to the presence of stud walls) but also because of the network of electricity & plumbing lines that run within the wall.
Mark the end points of your shelf carefully. Make sure the lines go straight or else you will end up carving a sloping shelf. Once done with the marking, use a wallboard saw to cut the shelves. Use lumber to make the shelf planks. Install them using properly aligned screws.
