Select the letters you want to use. Then, click on the "Ungroup" button. This will allow you to move the letters around independently. If you want to make the letters bigger or smaller, you can use the "Scale" tool. Just click on the letter you want to resize and enter the new dimensions. Once you're happy with your design, click "Group" to put the letters back together.
You can then send your design to your Cricut machine and get started on your project!
