Before we get started, I want to be sure that you know that two days ago, on "Hello Thursday," quite a few new Cricut cartridges were announced. "Hello Thursday" is the third Thursday of the month and you should always check the Cricut.com site to find out about new products and check for Design Studio and Gypsy updates.
If you have the current version of the software (1.0.31101.0), you will only need to download and install the updated Font Pack. You can check your version by using the "help" menu and choosing "About" to pull up the information box.
If there is more than one cutting line for the letter part will be dotted red and part dotted black - it doesn't matter for nudging but it can be easier to see the part of the letter that will be welding if you click on the center of any letter with an interior cutout such as "o." As I mentioned in the tips last month, the first letter can not be nudged - it is positioned by using the handle at the upper left corner of the selection box.
