I have industrial machines and have a double layer of fleece wrapped around as an easy pincushion. Just checked, and the Brother logo plate has some pin-dinks in it but the enamel on the machine is perfect.
Actually it's a quad layer because I've serged two strips of fleece together and then wrapped that twice. Couldn't be bothered sewing velcro, it's held in place with two honking great safety pins.
I love it, I can always find the pins/handsewing needles etc I need.
