hiya pauline, i have a big shot, but i would think that you put the whole thing back through once it's cut, using a sandwich that raises it up enough to put enogh pressure on to emboss it. if this is not the case i would perhaps look for the cuttlebug site, they probably have the info you need on there, if i can find anything to help i will pm you m8.
you could try dipdoolally, she has a big shot but she has some emboss/die cut dual folders too. so she will know probably more how to use them.
