If you want to save money on your kitchen renovation, tiling your own backsplash is a great move—unless it's done improperly. Inexperienced DIYers often start tiling at one end of the wall and work toward the other side. When done this way by a novice worker, this can result in uneven or odd angles that look amateurish at best. To ensure a straight line when laying your own tile, start from the center of the wall and work your way from each side. Using this method, you'll find that your cuts will be the same on all sides of your project.
