For this technique you use two contrasting fabrics – one is focus fabric, the other background fabric. Cut 2 squares of each color for each block needed. (4 squares per block)

Cut rectangles of one of your fabrics.  Iron one edge ¼ “ under.  Fold side to center to form a triangle and press. You may make your triangles any size you wish – this is your creativity and design inspiration.
Sew the triangles to sides wanted and top-stitch down (folded or flat)

Example:
Small triangles of light fabric were sewn to 4 sides of dark fabric and stitched on bias fold to form curves.

Red/white pinwheel above is actually large triangle sewn to one side of each square – all squares same fabric.
