If you are starting from scratch, you probably need to use Photoshop or something like it.
Basically, you need to make all of your art and information fields seprately then size them and move them into position. Besure to start with the right dimensions, first! Lastly, blow up your image and clean up lines and spots and dots, etc. with the eraser tool.
Once you have one card good to go, you use Word/Tools/envelopes and lables/Labels (pick sheet style #**) and click full sheet of same labels)/new document.
** You may need to manually enter the dimensions as a "custom" label **
Then cut and paste your new card into the squares made when you click on Word/tools/Envelopes & Labels/New Document.
