if you don't cut cardstock with it, what do you use it for?
Everything else including all patterened papers, household stuff like recipes and thin cs. Don't get me wrong, I do use the trimmer for the odd piece of heavier cs but for cutting all bases and assembly line layers I use the tabletop trimmer.
I wish Fiskars made a rotary trimmer with the same dimensions as the SureCut and the SU new trimmer. What rotary trimmers they have are too short, too narrow or too bulky.
