Sorry to tell you Sue but if i'm not mistaken you can't use the Marianne designable folders in the calibur and i'm sure there was a post with a warning telling you not to use them in the calibur. You can use them in the big shot as thats how I use mine. Also you can use them in the cuttelbug but I can't seem to manage putting them throught my bug as there seams to be a lot of resistance and I don't want to force it throught in case I break my machine. If i'm wrong i'm sure someone who is more in the know than me will be able to tell you for certain.
