Finally! A way to create perfect corner triangles that works! The fabric fills the corner, the blocks are straight and the right size! This allows you to assemble your blocks without needlessly chopping off points and ruining the visual effects created by the quilt design. You deserve the best! Works with any corner triangle, especially those using the "sew 'n flip" method. Examples are: snowballs, square in a square, star points, flying geese, triangle on a triangle, and many more.
