Hi all, I have recently gone on a sewing machine course and loved it. I'm getting a janome 525s for my birthday this weekend and wanted to buy a walking foot/even feed for quilting. However, the janome brand ones are about £40. I have seen universal ones on ebay for far less, but I was worried that they wouldn't work or could damage the machine. Do I need to buy a janome brand one? I'm totally clueless about all of this at the moment. Thank you!
