I am not sure -Maybe You can! I thought I read you only could use the long border dies with the Sidekick (cause of the long cutting pad you will need to use & it wouldn't
work with the larger sizzix.) My LSS doesn't carry Sizzix so I just have to order them in the mail - no salesperson to actually talk to - I guess if I called Sizzix they would be glad to answer the questions...
If anyone hears/reads differently, let us know.
