Cutting Instructions:

  1. Cut 1 rectangle (feature/larger print): 4 by 5 1/2″ (10 x 14 cm).
  2. Cut 2 strips each: 2 by 5  1/2″ (5 x 14 cm), 2 by 7″ (5 x 18 cm), 2 by 8  1/2″ (5 x 21 cm), and 2 by 9 3/4″ (5 x 25 cm).
  3. Cut 2 squares: 6  1/2″ (15 cm).

Piecing Instructions:


  1. Lay out the central 4 by 5  1/2″ rectangle right side up. Place both 2 by 5  1/2″ strips on top and bottom of the rectangle, lining up the 5  1/2″ sides.
  2. Place the pieces RST and sew a 1/4″ seam to begin forming the central unit. Press seams open or to the darkest side of fabric.
  3. Place the 2 by 7″ strips along the 7″ side of the central unit and sew RST. Press seams.
  4. Continue adding the 2″ by 8  1/2″ and 9 3/4″ by rotating sides as you add the next set of strips. See figure 1 below.
  5. Fold the central unit in half and press with the iron to create a central crease. Fold opposite direction and repeat so each edge of the block has a creased central line. See figure 2 below.


  1. Take the two 6  1/2″ squares to the iron. Fold each in half with opposite corners touching and press to form a central diagonal crease.
  2. Cut each square along the diagonal to create 4 half square triangles. Fold each triangle in half with the points on the longest side of the triangle touching and iron for a central crease.
  3. Line up the crease of the triangle with the crease of the central unit and pin in place. Repeat for the opposite side and sew. (See figure 2 below.) Press the entire block flat.
  4. Take the block to the cutting mat and trim to 12″ (30 cm) square to complete the block. A clear 12″ square ruler is advised. See figure 3 below.

    I donate baby blankets to hospitals in my location. This simple block would be perfect to give to Shop with a Cop or give to Fire or Police to provide for families in need.

    These easy quilts make great lap quilts for patients in Nursing homes. You can have family members all sign their names on the light colored borders and think of other ways to personalize a quilt for someone special. This quilt could easily be done in a loved ones favorite colors instead of just Christmas.
