Why create one? _ "Re_inventing the wheel", is no fun. If you work for a single organisation it's likely that your templates could last a long, long time with no need to go back to the design board every time you are asked to create a new manual or user guide. When you work for yourself it's a great way to show clients that you have the skills they are looking for without breaking any confidentiality clauses with your existing clients, and with just a little bit of luck they'll adopt your method of working so you can continue to recycle your past efforts too.
As you can see, creating your personalized labels is really not so hard as it may seem. Why settle for something that is not exactly what you want, when you can make original and creative templates yourself? Just take the time to give it a shot. Creating templates is quick and easy, and having special labels created by you will give you a great satisfaction.
