I have the Brother Hs2000, but this is where I got my walking foot and FMQ foot. They have a lot of Brothers parts. If you have an owners manual, it will give you the numbers to look for or you can find the manual online. I love mine! Both of them! DH got them for me for Christmas and I've been using them ever since.
