Construct the Triangle SquaresWe'll use a quick piecing method to assemble the triangle squares. I think of it as the 'sandwich technique.' Use another method if you prefer, but alter cutting instructions as necessary.
- Draw a diagonal line from one corner to the opposite corner on the reverse side of each light square. Pair each light square with a dark square, right sides together and all edges matched.
- Follow the instructions in my quick pieced triangle square method to sew each pair of squares together. Cut apart and press as directed.
- You should now have 16 triangle squares that measure 3-1/2" x 3-1/2". Make additional triangle squares if you do not want to repeat identical units in the same block, as each pair of squares produced two identical units.
- Arrange the 16 units into four rows as shown, each row with four units. If you prefer, flip the positions of dark and light fabrics. When making a quilt, alternating those positions from block to block is one way to create visual movement in the quilt top.
- Sew the four units in each row together. Press seam allowances in adjoining rows in opposite directions. Handle rows carefully to avoid stretch.
- Sew the rows together. Press the Depression quilt block. It should measure 12-1/2" x 12-1/2". If yours is off a bit, try one of my quilt block problem solvers.
