Click on the word 'Shaws' then select 'Ungroup' from the same menu.
Once each of the letters has been ungrouped, double-click on them to prompt a text box to appear, amend the letter as desired, and continue working on this way until all the letters have been amneded.
If more letters are needed simply 'Duplicate' the letters until you have enough, then amend each individually.
Reposition the letters as desired, then drag a selection box over the surname and select 'Attach' from the menu on the right-hand side.
