If you purchase a Catholic Catechism, you have to get these tabs!!! There are tabs for each of the major sections, so you can navigate the book with ease. You will be the envy of all your friends when they see you quickly opening your Catechism to a section while they fumble through it hoping to find the table of contents to find the section and pages they are looking for. (If you know someone who has a catechism, these tabs make an awesome gift.) I do alot of bible studies and I need to be able to access my support materials and info quickly. These tabs really help me find things fast! The one piece of advice I must give anyone who purchases the Catechism tabs, or Bible tabs, is DO NOT just start sticking the tabs on the pages. If you do, you may end up with a messed up tabbing system. You want to be sure to FOLLOW THE DIRECTIONS EXACTLY. If you do that and use the tab line up template guide that is provided, your tabs will be perfect. Even if it seems weird to start from the back of the book or whatever it tells you to do, just go with it. It will work perfectly. (It's an exercise in faith! ha ha) Once your tabs are in your Catechism will be accessible and your searching time will be greatly reduced!
