Mystery Quilt 2018 Block Three

I hope you are enjoying this Mystery Quilt! So far we have demonstrated a quick and easy technique for Flying Geese and for partial Log Cabins.

This week we will learn to make pinwheels. Using colors #2, 10, 13 and 14 as well as one of the 12 ½” x 24 ½” rectangles cut in step one and your background fabric, cut the following:

From EACH of the four colors, cut two 5 ½” squares.

From your background fabric, cut eight 5 ½” squares.

Step 1). Pair one background square with one color square, right sides together.

Step 2). Sew a ¼” seam around all four edges of each of your paired 5 ½” blocks.

Step 3): Cut each sewn square unit in half diagonally in both directions.

Step 4): Set your seams, open cut triangles and press to the dark side.

Step 5): Square up the half square triangle blocks to 3 ½”

Step 6): Lay the four half square blocks as shown below. You can use four blocks of the same color or get happy and mix your blocks up! It is your choice!

Step 7): Sew the two top units together with scant ¼” seam. Press.


Step 8): Sew the bottom two units together with scant ¼ “seam. Press.


Step 9): Sew the top and bottom units together with a scant ¼” seam. Press.

You have completed One Pinwheel Block. Do this with all units to make Eight Pinwheel Blocks. Square up to 6 1/2 “.

Step 10): Sew Four Pinwheel blocks together in a row. You chose the order you want your colors. Press

Step 11): Do the same with the four remaining Pinwheel Blocks. Press.


Step 12): Attach the Pinwheel rows, one row to each 24 ½” side of the 12 ½” x 24 ½” background Rectangle.

Mystery Quilt

  Block Two

1)      You need one of the 12 ½” by 24 ½” rectangles cut from your background fabric during Block One.

2)      Also, from your background fabric, you will need to cut Sixteen 3 ½” by 3 ½” squares.

From colors #1, 3, 14 and 15, you will need to cut FOUR from EACH color:

3)      Four 2 ½” x 2 ½” squares, label as B

Four 2 1/2 x 2 1/2 squares from each of four colors  

4)      Four 1 ½” x 2 ½” rectangles, label as C
Squares and 1 1/2 x 2 1/2 rectangles

5)      Four 1 ½” x 3 ½” rectangles, label as D
All pieces cut

Here is where the fun can begin, you can play with all your cut pieces until you find a color combination you like. Basically, you want one “B” square with one “C” rectangle and one “D” rectangle attached as if beginning a log cabin block.

Play with color combos

You can have each piece a different color, you can have the square one color and the two “logs” the same color but different from the square or you can even have all three pieces the same color. Play with it until you like the color combination. Lay out your combinations in order, for easy chain piecing.

6)      With right sides together, sew your unit C to unit B. Do this with all B and C units. Press the seam to the darker side of the two fabrics.

7)      With right sides together, sew unit D to the B/C unit. Chain stitch all together for faster piecing.

8)      Next, take your background 3 ½ x 3 ½ squares. Sew one B/C/D unit to one background square. Sew another B/C/D unit to the opposite side of the background square. Continue to alternate the B/C/D unit and background until you have sewn eight together. Four B/C/D and four background. You should start with a B/C/D unit and end with a background square.

Repeat Step 8, but go in the opposite direction with your colors. When both rows are complete, press seams (do not iron as it could distort small blocks, press and lift iron)

9)      With right sides together, sew your completed rows to the center 12 ½ by 24 ½ rectangle. One Unit on each side of the background rectangle.
