Prismatic Star was originally published in 2014 to show how an exploded star could be paper pieced. The pattern was updated in 2018, making the diamond block slightly larger and creating templates for the sashing strips that reduce the number of stacked seams during assembly. While the original design has been a great pattern for Quiltworx, these improvements to the pattern will make assembly easier. At the same time, we have created a series of diamond blocks that are identically sized to the Prismatic Star block and interchangeable. This allows you to customize a quilt project in either a wall layout or a queen layout to create something unique. Pattern Size: 68" x 68". Pattern includes: Instructions, Cover Sheet, Yardage Information, Foundation Papers.
