Dioptra is comprised of a network of stars, their connections weaving together through their points, plotting a path across the sky. The pattern is named after the dioptra, an ancient Greek surveying device that allowed users to make large, complex measurements - say, determining the distance between Rome and Alexandria - based on the positions of the stars.

Dioptra’s stars include some unique angles, achieved through either foundation paper piecing or standard piecing with a bit of trimming (it’s up to you). Full instructions included for foundation paper piecing in case you’ve never tried it and would like to give it a try. Please note that you will need to either copy or print additional paper piecing templates if you choose to paper piece (templates fit on US Letter / A4 paper).
