What can you do with a half square triangle?  The possibilities are endless.   Any pattern for log cabin quilts can be done with half square triangles in a fraction of the time.   Above are three radically different layouts.  The first is made by grouping the green fabrics to create a Christmas tree against golden beige fabric.  Look closely and you can see that a few blocks were fussy cut to feature cardinals.   The second layout reminds me of a southwestern star.   Now imagine the same pattern with bright gold fabrics against a navy background.  A totally different look.   The third quilt orients the dark part of the square in the same direction.   Easy-Peasy!   Quilting was done with a cotton variegated thread to bring out the colors of the fabrics.   What can you create with half square triangles?
