I get these things in my brain and can't let go until I get the answer. I fast forwarded the episode on the website and they're saying "marrow" and "marrowing". So, I looked that up and found my answer. It's a Merrow sewing machine. From the show, it seems their well known in the design world if their making verbs out of the name. I went to the Merrow website and each machine is designed for one or two specialty stitches and the lowest price is $2650.00.
