Useful but could be improved
Ruler work is great for those of us who struggle with free motion quilting, however these rulers, well-thought as they are, have a couple issues: the ruler doesn’t grip to the fabric with pressure as advertised, and the push of the foot on them makes them slide off course. The little leg on the Petunia is also very fragile, it broke at first use. MSQC was gracious enough to send a replacement.
