I just got a cricut last night so I cant wait to figure out how to get all your digital goodies over into that format! Hopefully its not too bad with the missing outline function haha
You do the offset to add bleed around the sticker (for the white border)! You don't have to add an offset line if you don't want to but it's useful because it's more forgiving for the silhouette machine since there's always a margin of error while cutting.
