This is Sew-In Interfacing (which means non-fusible) in a light to medium weight especially for use in Lori's machine and hand applique methods using her Sew Simple Shapes Templates and specialty Bee in my Bonnet Rulers.

This is the interfacing used for her Sew Along to make her Cozy Christmas Quilt using her Cozy Christmas fabric collection for Riley Blake Designs. Contains 3 yards of 20in wide interfacing wrapped on a cute little bolt to keep it tidy.
