Oklahoma Twister Quilt Block Pattern

I have made the Oklahoma Twister quilt block before, but I managed to place one of the half square triangles wrong, so I am writing the pattern again.  This time with the triangles all correct, I hope!

In order to save time, I have also used white rectangles equivalent to either two or three white squares.  The block as I’ve made it is an 18″ square.

Cutting requirements for the Oklahoma Twister quilt block

3.1/2″ squares:  six white

6.1/2″ by 3.1/2″ rectangles:  four white

3.1/2″ by 9.1/2″ rectangles:  two white

3.7/8″ squares:  eight red, eight white

The half square triangles

Use the 3.7/8″ squares to make the half square triangle units.  Place a red and a white square with right sides together and mark a line along the diagonal.  Sew a 1/4″ seam either side of the marked line and cut along the line.

This will produce two half square triangle units which are now 3.1/2″ squares.  Press the seam allowances towards the red and trim the two corners where fabric sticks out.

Lay the patchwork pieces out in six rows.  It may look like a maze of half square triangles, but just take it slowly and look at small sections.

First of all, in the middle is a red/white pinwheel formed by four half square triangles.  From each blade of this pinwheel extends a white rosebud shape formed by a square and two triangles.  In the top left the rosebud is to the left of the pinwheel triangle while in the top right the pinwheel is above the pinwheel triangle.

Place the white rosebud to the right of the bottom right pinwheel triangle and beneath the bottom left corner of the pinwheel.

The 9.1/2″ white rectangles are placed in the top and bottom rows, while each of the other rows contains a 6.1/2″ white rectangle.

Sew the pieces together across each row and then sew the rows to each other to complete the quilt block.

For the basic quilt design, I have shown nine blocks sewn together in three rows of three.  This gives quite a pleasant swirly look to the quilt.

For an alternate idea, I changed the white rosebud shapes to light blue and this changes the look to a distinctly floral effect.
