Rocky Mountain Chain Quilt Block - a Free Tutorial

By: Elaine Huff

The Rocky Mountain Chain block uses easy pieced patches that join to form a complex-looking block. Let's create one using four colors! The traditional block only uses a light and dark fabric but I had to do it my own way!

This block also goes by the name "Tumbling Block" but so does another popular block that is more commonly known. So I'm sticking with Rocky Mountain Chain which was how it appeared in the Comfort Magazine. 

Fabric Requirements for a 10" Finished Rocky Mountain Chain Quilt Block:

  • Light/White: 4 - 3" squares, 8 - 1.5" x 2.5" rectangles, and 16 - 1.5" squares
  • Medium/Orange: 4 - 3" squares
  • Medium/Blue: 5 - 2.5" squares
  • Dark/Navy: 8 - 2.5" squares

Sewing Directions:

Half Square Triangle Units:

Step 1:

Using the Light/White 3" squares and the Medium/Orange 3" squares, piece together eight Half Square Triangles like the ones in the picture below. Trim/square up to 2.5" squares. You can find the tutorial for making a basic Half Square Triangle block at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-half-square-triangle-block

Square in a Square Units:

Step 2:

Using four of the Dark/Navy 2.5" squares and the 16 Light/White 1.5" squares, sew together four Square in a Square patches as shown in the picture below. I know these are small, but just take your time and they'll turn out great!

Step 3:

Lay out one of the Step 2 Square in a Square patches and two of the Light/White 1.5" x 2.5" rectangles as shown below.

Step 4:

Sew the two Light/White 1.5" x 2.5" rectangles to the Square in a Square patch and press the seam allowance toward the rectangle as shown in the picture below. Repeat Steps 3 and 4 for a total of four Square in a Square units.

Corner Units:

Step 5:

Lay out two Half Square Triangle units, one Medium/Blue 2.5" square, and one Dark/Navy 2.5" square as shown in the picture below. The Corner unit goes together like a typical Four Patch block.

Step 6:

Sew the patches into two rows and press the seam allowances away from the Half Square Triangle units as shown below.

Step 7:

Now sew the two rows together and press the seam allowances. You can see in the picture below that I used the tweak/twirl/furl method for pressing the seam allowances, but you can press however you prefer. Repeat Steps 5 through 7 for a total of four Corner units.

Putting It All Together:

Step 8:

Lay out the Square in a Square units, the Corner units, and a Medium/Blue 2.5" square as shown in the picture below.

Step 9:

All that's left is to sew the units together like a uneven Nine Patch. Sew the units into three rows as shown below.

Conclusion:

This block was fun to piece together! While it has a some small pieces, the piecing isn't difficult and produces a complex-looking block.

Layout Options:

Here's just a plain Jane 4 x 4 layout. I do like the way it looks in a quilt.

Here's how it looks with a simple sashing and cornerstone layout. Each block shines on its own in this type of layout.

And here's a basic on-point layout. I think if the setting triangles continued the Medium/Orange triangles, it would look better.

And here we have on-point with sashing and cornerstones. In this example, I used a 1" wide sashing and I like it better than the 2" in the other example above.
