The Little Rotation Bobs are for marking evenly spaced rotations when using tools such as the Spinning Waves, these are great for use when quilting on a domestic sewing machine.

Ruler foot is not included and must be purchased separately if you do not already own the foot

I was totally satisfied with my experience. I sent a lot of time at the site and found it very easy to navigate. It would be nice, though, if there was a separate category for the Westalee products that would allow a shopper to see all of the products at once without continued re-searching. I probably would have purchased more items if it would have been easier to compare choices.
