Sounds like she might be using the bonded fabric blade which is an option but she shouldn’t need to use if she has the maker which can handle fabric with the little rotary blade (the other machines can’t use the rotary blade so they have to use the bonded fabric blade). Glad it sounds like she’s found a way forward!
Eta - the main benefit of the maker with fabric and the rotary blade is you don’t need to prep the fabric at all. I have cut lots of quilting cotton on my maker without doing any prep to it (no interfacing or freezer paper, etc).
