Here are a couple of example layouts to give you ideas:

Now - type in your required text in the 'line' boxes below
 
Design guide:  

1. Each box represents one line of text.
2. Maximum of 15 lines.
3. Don't let the text go beyond the ends of each box. 
4. For a different font size - tick one of the small boxes to the right of the line [s-small,
   m-medium, L-large] (changes to font size will only be seen in the preview page).
5. Tick the small box labelled U to the far right of the first line if you want that line underlined as a heading.
6. Number of characters is limited to 480 in total (an average of about 30 on each line if all 15 lines are used but a higher number per line can be squeezed in if you don't use all the lines). Just keep a watch on the 'characters used' and 'number remaining' boxes which change after each line is completed.
7. enter one or two spaces if you want a blank line.
8. jump between this page and the preview as many times as you like.
9. clicking 'clear text lines' will delete the text you have entered and zero the number of characters used.
