The word or your choice will be kept in proportion to the width chosen - EG. If you choose 5 inches, and your word has 10 letters, each letter will be 0.5 inches wide and the height of the word will 'look' correct in terms of proportion.
Please choose your font carefully - if you would like the letters separate, check the 'flicks' on the end of the letters (in swirly/script font in particular) to ensure you are happy with the way each letter will look.
Options:
Width of word (3 inches wide, up to 12 inches wide)
Single or Joined letters (All letters individual or words joined together)
Font (Bold, Swirly, Serif or Script - please see imagery)
Thickness of Wood (2mm or 4mm)
