Hi Red,
I’m not sure which die you have but if they are big thick foam looking ones these will cut fabric as well and you will just need the clear pads (pad-die-fabric/paper-pad).
if they are thin pieces of metal (thinlits) these will only cut paper/card and you will need the multi purpose platform which is essentially a chunk of white plastic to make the sandwich thicker. Then you need platform-pad-die-paper-pad
sizzix have some good tutorials on their site
