And welcome to the QB.
QuiltnNan, your reply was right in. Just want to add a few comments. I have sewn for years but have found the patchwork foot WITH GUIDE to be very helpful. I have one machine (Pfaff Passport) which is my designated piecing machine. The seams are perfect width. I also have a Bernina. It is so frustrating because I have to move the needle to get the perfect 1/4" seam. I use this machine for FMQ and embroidery.
