I have a Viking Designer Royale, and accessory feet are available through your Viking dealer. There is the Clear 1/4" Piecing Foot with Guide, part no. 412927445. It fits all codes, and the Sapphire 875Q, 870, 855, 850, 835, 830 are all a code 7. I also have a Pfaff Performance 5.0, and there are accessory feet for piecing for it as well, a 1/4 " piecing foot without the guide comes with it, and there is also the Clear Quilt Foot Right with IDT, 820881-096, and the newer one Perfect 1/4" with Guide which has a little wider hole for moving your needle in order to do the scant fourth inch. Part no. is 821063096 and works on Pfaff coded machines B, C, D, E, F, G, J, K. Love this foot, but have to always remember to move needle over because machine defaults to center needle when machine has been turned off.
