I have a 190 named Sven and don't FMQ with him. Two years ago, I invested in a Viking walking foot ($$$). Looked to see what would work for FMQ. Probably foot #411 73 90-01, the Darning Foot. I am curious to hear what you find for this! I love my 190 so much I bought another one on Ebay. It sews anything I throw at it.
