I haven't had time to play with mine realy so tonight I decided to just try it with one of the frosting sheets.
It cut perfect first try!
I set it to High pressure , mediun speed .
The one thing I think that is crucial is to make sure that whatever you are usng is stuck to the mat really well.
Too much shortening and it will slide and pull , tear, etc. Too little and it will move while cutting.
When you get the right amount it will stick firmly to the mat ( it is hard to push it around, feels like it is glued to the mat)
Here are my first cuts with the frosting sheets.Will try gumpaste in the next day or so cause the frosting sheets taste TERRIBLE!
