I use the border function to make these guiding lines:
In word 2007:
Step 1: Go to Page Layout ribbon
Step 2: Click on page borders
Step 3: Click on first tab (Border)
Step 4: Click on custom
Step 5: For your first solid line select your font style, colour and width e.g. default solid option
Step 6: Click on top line in preview box and press ok
Step 7: Press enter key to enter a space
Step 8: Now, repeat steps 1 to 7 but select dotted style
Step 8: Repeat Steps 1 - 7 for your bottom solid line
Then, copy these three lines and paste them where you need them
You can find ready made sheets at:
