Use SewTites® Boosters magnets with the Sew Magnetic™ Mat and Ruler of your choice to:

• strengthen the hold of your ruler when cutting ultra-thick materials and fabrics
• hold down paper pattern pieces without pins
• hold down acrylic templates without pins

Please note: Boosters will not hold to a regular self-healing cutting mat. You also need a Sew Magnetic Cutting Mat (sold separately).
