The Scrappy Half Square Triangles and Squares quilt is made with squares and half square triangles using light and dark scraps. The light fabrics are low volume prints.

Sew 2″ finished squares to make 4-patch units that finish at 4″. The half square triangles are 4″ finished. The block is 16″ finished.

The quilt pictured here is 64″ x 80″. There are 20 blocks set 4 across and 5 down.

The block is a made up in a 4 x 4 grid. Each grid unit has either a 4-patch unit or half square triangle that finishes at 4″.

To make the block smaller, simply make the unit in each grid 3″ finished for a 12″ block or 2″ finished for an 8″ block.

An exploded view of the block is shown. The 4-patch units and the center 16-patch unit can be strip pieced for faster piecing.

Most importantly, pay careful attention to the placement of the dark fabrics.
