I am still trying to figure my Cricut out, but Ashley says that In order to use a SVG file with your Cricut you will need a software called Sure Cuts a Lot — which allows you to cut any True Type Fonts, and shapes from your computer. You don’t have to buy cartridges anymore! You can purchase the software here. They also have a huge forum where you can download tons of images ready to cut.
Once you have the software installed, there is a button that looks like a little present and says SVG on it. You click on the button and choose your SVG file to import. Then you can size it how you need it and print it to your Cricut machine. So much easier than cutting it out.
