Autumn Tints Quilt Block

From our Free Quilt Block Patterns Library

Our Autumn Tints quilt block uses traditional piecing techniques—including making half square triangles 8-at-a-time—to complete this rather modern-looking patchwork design.

Lots of negative space to play with!

As with all our blocks, you'll find:

Cutting directions for multiple sizes: 7", 10-1/2" and 14" finished,

Step-by-step instructions to make the block. Pressing directions are always included to make construction as foolproof as possible.

To spark your creativity, you'll also find:

Layout ideas for both straight and diagonal sets

A cutting chart for stitching up this design into a bonus quilt for all the scrap lovers

Two contrasting fabrics are all you'll need for your own Autumn Tints.

It's to to cut up and sew!

General Instructions

Pin the Autumn Tints block tutorial for later

Several abbreviations are used in this lesson. They are:

SA - seam allowance

RST - right sides together

HST - half square triangles

1/4" SAs are used throughout this tutorial.

When instructed to press, press the patches in the closed position first—just as they came off your sewing machine. This sets the seam, melding the fibers of the thread into the fibers of the fabric.

Then press the SA to the dark unless otherwise noted.

Starch makes everything easier—in my opinion. A 50/50 mix of StaFlo Liquid Starch concentrate to water is my favorite recipe for truly stable patches.

Other quilters prefer Best Press. Use whichever works best for YOU.

Step 1: Cut fabric for an Autumn Tints quilt block

Autumn Tints
Design attributed to Nancy Cabot

Sample Block Size:

10-1/2" finished
10" unfinished

Two fabrics are all you'll need.

To ensure that all your sharp points will show after piecing, choose fabrics with high contrast.

While the fabrics chosen for the sample are pretty together (the block is more vibrant in person), a couple of points aren't as pointy looking as they could be. That's because the same color in the same value is in both the light and dark fabrics in our Autumn Tints block.

It's always a good idea to make a sample block to test your choices!

After cutting label your patches.

Step 2: Assemble the units for your Autumn Tints

HSTs

Make 16

We use the 8-at-a-time method to make the 16 HSTs needed to complete this design. If you're making many blocks, you might want to try triangle paper for even more efficient piecing.

To begin, draw two diagonal lines on the back of either the large #1 or #2 squares.

Below you can see that I've marked the darker of the two. This is because my chalk markings are easier to see. (I've used my Bohin Mechanical chalk pencil for this—my personal favorite.)

Stitch a 1/4" from both sides of both lines for both pairs of patches. (That's a mouthful! :D )

You can barely make out the chalked diagonal lines. They only need to be as dark as YOU need to see them.

Rotating rotary cutting mat available from Amazon.com

My favorite mat for trimming HST—very efficient!

After stitching give your sewn pairs a good press, then move to your cutting mat.

I use a rotating mat for easier trimming. Just load it up with HST and trim away.

Using the chart below, find the finished size of your block and the corresponding Center or Midpoint Measurement.

For our 10-1/2" sample that measurement is 2-5/8".

HST Dimensions
Finished Block Size	Center/Midpoint Measurement	Trim HST to…
7"	2-1/8"	1-1/2"
10-1/2"	2-5/8"	2"
14"	3-1/8"	2-1/2"

Find that measurement on your ruler and align that line with one edge of one sewn pair (red arrow). The edge of your ruler should be in the middle of the block. Cut through the center.

Cut #1/#2 in half through the center vertically.

Turn the mat a quarter turn (this is where the rotating mat is so nice—there's much less disturbance of your patches.

Align the Center measurement with the edge of your pair of patches and cut through the center again. You now have four equal squares.

The blue arrow shows that the orientation of the mat changed when you rotated a 1/4 turn.

Cut the square apart on the diagonal lines to form the HST. Because your squares haven't moved these cuts are quick to make.

If you've not disturbed your patches, you'll be able to use your rotary cutter for these last two cuts.

Repeat for the second sewn #1/#2 pairing.

Press your HST with SAs towards the dark.

Referring to the chart, find the 'Trim to...' size that corresponds to your block and trim your 16 HSTs to perfection.

For our 10-1/2" sample, the HSTs are trimmed to 2"x2".

HST Units

Make 4 of each

To complete our Autumn Tints block, you'll need four pairs each of mirror imaged HST duos.

With RST, stitch pairs of HST together so that 4 pairs have dark HSTs that slope down to the right and 4 pair that slope down to the left.

For the pinners out there...

...yes, I pin these so that the edges stay even.

SA are pressed toward the dark fabric as shown below (red arrow).

Make 4 of each

Corners

Make 4

You'll need 4 each of #3, #4 and #5—it's a good thing you labeled your patches.

With RST, join four #3s and #4s together. Press the SA toward #4.

With RST, join the #5 to the pair. Use the picture below to make sure that the patches are joined exactly the same manner. You'll want the #5 on the left side with #4 in the upper right corner after sewing.

Press the SA in the direction of the red arrows.

Compare the dimensions of your units at this point to the chart below. Make any needed adjustments.

#3/#4/#5 Dimensions
Finished Block Size	Edge-to-Edge Measurement
7"	2-1/2" x 2-1/2"
10-1/2"	3-1/2" x 3-1/2"
14"	4-1/2" x 4-1/2"

To complete the corners, arrange the sewn HSTs, a #3 patch and a #3/#4/#5 unit as shown below.

With RST, join the units, pressing SAs in the direction of the red arrows after each seam is complete.

Repeat for a total of four.

Check your dimensions against the chart below, adjusting if necessary.

Corner Dimensions
Finished Block Size	Edge-to-Edge Measurement
7"	3-1/2" x 3-1/2"
10-1/2"	5" x 5"
14"	6-1/2" x 6-1/2"

Step 3: Assemble your Autumn Tints quilt block

Arrange the pieced corners and cut rectangles and square into the Autumn Tints design. The corners are positioned with the dark square towards the center of the block.

Patches arranged to form the Autumn Tints design

With RST stitch the units together in each row. After sewing, press the SA in the direction of the arrows.

With RST, sew the rows together. Here I'ved pinned to help keep all the edges even. It's easier that way to pay attention to your quarter inch seam at the points of the HSTs.

Note, too, that the side with the most piecing is on top to minimize Twisted Sister seam allowances.
