My final verdict on this foot is that I really, really, really wish they had made the foot a standard 1/2 inch in diameter. That makes spacing a big issue and it won't work with rotating rulers like the TopAnchor Quilting Tools. I also am not wild about it being a hopping style foot, but that does have advantages when it comes to bulky seam intersections. The hopping isn't a deal breaker. I wouldn't choose it over my Janome foot, but that's me. The price is approximately $75 US, including a sew slip mat and ruler, not sure about shipping. Wish it could be bought with just the foot. It comes in low 'reach', high 'reach', and Bernina version. I don't like the rulers. You have to cut your thread to take the ruler on and off the project- no groove for threads to slide out of the center.
Now I am off to care for my little guy who has pink eye and strep. Why did I ever send him to daycare? Besides sanity and a need to work. Poor fella.
