ClipArt can dress up any document. ClipArt should be inserted after you have your document typed. This will give you a feel for how much, and the size for your clipart.
If you are using any of the Microsoft Office software, or some other computer software, the process is very similar. By knowing Microsoft Word well, you will be able to transfer this knowledge to most other programs with minor changes.
A good rule to remember is 75% text and 25% graphics. This is not a hard and fast rule, just a guideline for balance. Some of the mistakes new users make is that their graphics are too large. Do not use clipart to "fill up the page," it would be better to have white space.
