From Silhouette America:
Silhouette Studio gives you the ability to create Silhouette projects. You can download Silhouette Studio even if you don’t have a Silhouette electronic cutting machine yet. That way you can practice creating projects using the software’s design tools and the fonts on your computer. You can also build up your library and take advantage of Silhouette Online Store sales and promotions. You can even begin collecting the weekly free shapes to use once you finally get your Silhouette.
