I think the person you might be referring to is Leah Day -
https://www.leahday.com/art-quiltingspace/
I think this is the link to her website where she has information about the set up you are referring to - she does remarkable FMQ on a domestic sewing machine.
She also has lots of information/designs in her "freemotion project" website. You can just google it.
Good luck,
