What is wrong with using Word or Excel when designing my marketing materials?
For trivial jobs, these programs would suffice. However, they are not adequate when your goal is creative design for marketing purposes. The results are usually compromised due to the limitations of the tools in the software. For the best results, use one of the more powerful layout and design programs such as Adobe In-Design or QuarkXPress (at the very least, Publisher). Try to only use Word or Excel for their intended purposes; Word should be your word processing program and Excel should be used for spreadsheets and calculations. If Word or Excel is all you have, see below for some tips that might help.
