I LOVE a star quilt! Having larger shapes in acrylic templates allows to play with my made fabric, and design within the shape!  This diamond makes 4 different sizes of stars, with corner squares and quarter triangles marked on the template, for reference.  Finished Size of the largest size Star is 21.5"

Below sedan example of thinking beyond the star... works perfectly with my LARGE acrylic Diamond template. Four of the small diamonds equals one LARge diamond..Scrap bust! Goes to gather quickly! Very Impressive! ;-)
