I was gifted a used Silhouette SD and use it for big projects. (don't have a permanent home for it yet) I just cut 50 fancy frames out of Bazzil paper. Had to replace the blade near the end, but it cut beautifully. (Blade setting on 4 and did a double cut). I also designed a small wall quilt in the Design Software and had the machine cut the fabric for that. The quilt turned out perfect and better than if I cut the pieces by hand.
I finally bought some of the Silhouette individual designs after owing it for a year and using free designs all over the place or creating my own.
