Free Mrs. Keller's Nine Patch Quilt Block Tutorial

Posted by Elaine Huff on

Mrs. Keller is a variation of the beloved Nine Patch quilt block. This scrappy version is a stash buster for sure. The traditional design is made with just a light and a dark colored fabric but you could switch it up however you want. Let's get sewing!

Sewing Directions:

Half Square Triangle Units:

Step 1:

Using the two Light/Ivory 3" squares and the two Assorted Prints 3" squares, sew together four Half Square Triangle (HST) units as shown in the picture below. Trim/square up the units to 2.5" square. You can find my tutorial for making a basic Half Square Triangle at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-half-square-triangle-block

Rectangle Unit:

Step 4:

The Rectangle unit is constructed just like a Flying Geese block except that a longer rectangle is used. First you draw a diagonal line from corner to corner on the back of the remaining Assorted Prints 2.5" squares and sew them to each end of a Light/Ivory 2.5" x 6.5" rectangle (top image). Then match up the corners, press (2nd image), and trim the seam allowance (3rd image) to create the Rectangle unit (bottom image).

Putting It All Together:

Step 5:

Lay out the Half Square Triangle units, the Nine Patch unit, and the Rectangle units as shown in the picture below.

Step 6:

From here the block goes together like an uneven Nine Patch block. First you sew the units into three rows like in the picture below.

Layout Options:

Here's just a plain layout 4 x 4 with scrappy purple blocks.

The same as the one above but with cornerstones and sashing added. What a difference!

Here's an example done with just a light and a dark.

So with two darks and a light, this is what it might look like:

Put that same quilt on point. It always amazes me how different an on point layout looks!

Conclusion:

I had fun making the Mrs. Keller's Nine Patch a scrappy block. I'm always looking for scrappy designs to try and use up my scraps/stash! Other than the four intersections at the corners of the center Nine Patch being a bit bulky, the block was easy to sew together too.

Alternate Layout: I accidently laid out the units wrong at first - turned out to be a nice star pattern!
