These are by far the most magnetic magnets I have ever had the pleasure of sticking to my refrigerator. They can hold 6+ sheets of paper securely on a magnetic surface. I have also been known to use them as stud finders when I'm hanging things on the wall. 
 
This set of 5 magnets features a variety of vintage quilt fabrics. Each one measures 1 1/8" in diameter. Choose your selection from the drop down menu. You will receive the exact set in the photo.
