Part of making tight, accurate joints is to use a sharp knife to mark your lines instead of a pencil. Most marking knifes are beveled on only one side and come in right and left bevel versions. To start, I would go with either a right bevel one (if you are right handed), or a spear tipped, two-bevel one. More sharpening practice, too!
