This week’s block is called Susannah. There is an error in the picture of the finished block here below. The light squares in the sampler block should all be in the outer corners. One of mine got turned the wrong way during construction. The picture at the end of this post showing the layout also has one of the light squares is the wrong place. They should all be in the outer corners.
Cutting Instructions:
Light fabric #1 cut 4 squares @ 2 x 2 inches
Light fabric #2 cut 4 squares @ 2 x 2 inches
Dark fabric #1 cut 4 squares @ 2 x 2 inches
Dark fabric #2 cut 4 rectangles @ 2 x 3 1/2 inches
Take two of the light fabric #1 2 inch squares and two of the light fabric #2 2 inch squares and draw a diagonal line on the wrong side of each. Following the picture placement below, place these light squares right sides together with the 2 x 3 1/2 inch dark fabric rectangles and sew on the diagonal line. Pay close attention to the direction of the sewing line. 
Trim 1/4 inch away from the drawn line and press towards the triangle.
Pair the remaining light squares with the 4 dark 2 x 2 inch squares, right sides together and sew into pairs.
Arrange these pairs with the rectangle units as shown in the photo below, and sew together. Pay attention to the placement of the light fabrics, as I clearly did not. The light square in the bottom left section of the photo here is in the wrong spot. It should be flipped so that the light square is in the left bottom corner.
Go here for the finishing instructions, keeping in mind that the large triangles on the outside of this block are the light fabric.
