How Thangles Simplify Block Construction

Thangles simplify block construction because you eliminate calculating and cutting steps.  Let's see how
by making a shoofly block.   The shoofly block is a mixture of half square triangles and squares.  

We are going to make a 6" finished block.  The shoofly is a 3 x 3 unit block.  It is made with two colors of
fabric and it has a total of 9 pieces.  You need 4 half square triangles, 1 dark square and 4 light squares.

1.   Your calculating is easy.  All you do is cut a strip that is 1/2" larger than the finished size.  The
finished size is 2".  You cut a dark and a light strip that are 2 1/2" wide.

2.  Use the two strips and 2" Thangles to make 4 half square triangles.  The Thangles are 2 1/2" square
when they are made.  They match the strips.

3.  Go back to your strips and cut 1 dark square and 4 light squares.  These squares are the same size as
the Thangles pieces

4.  Layout the shoofly block and sew!  The unfinished block will be 6 1/2".   When it is sewn into the quilt
and the quilt is finished, it will be 6" square.  (You use a 1/4" seam allowance for all your seams.)
