They have a walking foot that has attachments that snap on, one is a 1/4 " foot and one is a stitch in the ditch foot, both work really well and are so useful. I use mine all the time. The 1/4 inch is really nice when attaching a border with your walking foot. It also comes with a regular foot and an embroidery foot. I've had my sapphire for 6 months and love,love,love it. I have the 875Q because I wanted the thread cutter, it also has auto tension. If you can afford it, I would suggest you get the 875. It is so worth it.
