Brimfield Block center acrylic template with 3/8 in. seam allowance by Brimfield Awakening. (The 4-piece acrylic template set is sold separately.) The orginal layout for the Brimfield Block Pattern (sold separately) has the center area of each block open, taking on the background fabric of the quilt once the block is appliqued. This acrylic piece allows you to fussy cut your center fabric, adding even more design options to your Brimfield Quilt! The Brimfield Block is designed by Kim Martucci and Nisha Bouri of Brimfield Awakening.
