When cutting sizes of material with the Silhouette which are smaller than the cutting mat, you will need to ensure you are placing your material correctly on onto the mat. Placement for smaller papers will depend on the Orientation selected in the Page tools options (which is the default panel open when the Silhouette Studio® program is started). Once you are ready to cut, go to the Send to Silhouette screen. You may then place your material exactly as shown on screen.
When using the cutting mat, please make sure you are continuing to load with the left side of the mat lined up with the guide mark on your Silhouette machine (as found in front of the left white roller) so that both white rollers are gripping the carrier sheet evenly.
