All screen resolutions are different so please note actual measurements. If you use any of the following symbols, we will use a centered dot by default: * (asterisk) . (period) - (dash) /(slash). So 10/10/2010 will come out 10.10.2010. (but the dots will be centered vertically). Click on picture to view samples and alternate views. LARGE & SMALL FONT Characters including spaces are as follows: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 1 2 3 4 5 6 7 8 9 0 . & ? We also have a heart symbol. If you want to order it, please use the "$" sign where you would like the heart to appear. You may also mention that you want a heart in the 'additional commments' box. We can make a dash or comma out of our small font letter 'I' but in most cases we feel a dot looks better. Letters are only available in uppercase.
