Here are a few alphabet charts you can use to sign your work. The heights assume you are using mixed upper and lower case; less space is required for all upper or all lower case.
I have only recently found your site, and encouraged by such beautiful designs, decided to order 2 patterns very recently. Imagine my surprise and delight to find them in the mail box already...I am so excited, I can't wait to start stitching! The patterns look very professional and easy to use and the spiral binding is a great asset. Thank you again Scarlet Quince from a new customer in Australia.
