Ready to show off your quilting skills?

The Texas quilt block is a fun little block that uses the 'Peaky and Spike' unit (AKA a Triangle in a Square) popularized by Doreen Speckmann many years ago,

You might also recognize the basic design of this block as a 54-40 or Fight. There's an extra fabric in that version of the patchwork design.

Instead of using a specialty ruler to make ours, we're using a bit of paper piecing—perfection every time, and it's not a big deal to remove the paper pattern from this particular unit. (The pattern is a free download below.)

You won't be messin' with Texas if you give paper piecing a try.

It's a game-changer for improving the accuracy of your piecing with little effort.

This tutorial has step-by-step, beginner-friendly, illustrated instructions plus a few other goodies for you to download.

Ready? Time to cut up!  And SEW!

General Instructions

You'll see several common abbreviations used on this page. They are:

  • SA—seam allowance
  • RST—right sides together
  • TiaS—triangle in a square
  • 4P—four patch

1/4" SA are used through this tutorial. 

Pressing instructions are highlighted in yellow throughout this tutorial to make them easy to spot.

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

Then press the SA to the dark unless otherwise noted.

Download and print the TiaS paper piecing pattern

Print the paper piecing patterns you need

You'll need the most current version of Adobe installed on your computer to download the pattern.

On the Adobe Print Menu page, under 'Page Size and Handling' set 'Custom Scale' to 100% before printing for accurate results. Click here to see what it looks like on the Print Menu page.

Choose your finished block size from the chart below and print the corresponding number of pages for the paper piecing patterns and a single copy for the templates.

DO NOT select 'Fit to Page' or 'Scale to Fit' in your printer settings. Doing so enlarges or reduces the templates and patterns. They will be the wrong size and need to be reprinted.

Step 2: Assemble the units for a Texas quilt block

With RST, sew a #1 to #2 along the long edge.

With starched quilt fabrics and my trusty 1/4" foot with a flange or guide on the right-hand side, this is a piece of cake.

Just don't sew so fast that your seam allowance gets wiggly.

Sewing #1 to #2Stitch the #1/#2 strip set


Use the chart below, find YOUR finished block size and the corresponding Strip Set Width. Check that your strip set measures correctly. Make changes as needed.

StripSet Widths

Block Size
Stripset Width after stitching SubCut Width
6" 2½" 1½"
9" 3½" 2"
12" 4½" 2½"

At your cutting mat, with your rotary cutter and ruler, straighten one short side of the strip set, creating a 90° angle to the seam.

While these strips are generously sized, trim away only what you must to straighten the edge. 

Straighten one short edge of your strip setThe red arrow points to the line on my ruler that's directly over the seam allowance.

Using the chart again, find the 'Sub Cut Width' that goes with your block size. For our 9" finished sample, the Sub Cut Width is 2".

Cut a total of 10—two for each four patch.

Pairs of squares ready to stitch into 4-patches

Alternate the patches to match the lights and darks of the unit (diagram above).

With RST, stitch pairs of these subcuts together, pinning if needed for a good match at the center. Feed them all through your sewing machine so that a dark #2 patch is on top and feeds through your sewing machine first. 

Sewing pairs of subcuts togetherYep. I'm a pinner—even for 4-patches. I admit it! :)

To reduce the bulk in the center of our 4-patches, we'll twirl or fan the SAs.

Undo the few stitches at the center—DO NOT cut away these thread tails. Leave them.

Then twirl or fan the SAs around the center. A cute little four patch forms in the SA.

Twirl the center SA to reduce bulk

At this point, for a 6" finished block, this unit measures 2½" square from edge to edge. For a 9" block (shown here), it's 3½" x 3½", and for a 12" finished it's 4½" x 4½".

Double check and make any adjustments. Then set these aside for now.

My go-to method for making this type of patch is paper piecing.

If you groan at the thought, allow me to explain why—and know that I've got a ruler technique to help you out if you just can't bear the idea of paper piecing. 

With paper piecing, I don't need to go find THE specialty ruler...and more importantly, its instructions.

I don't make TiaSs all the time, so my old tottering brain cells do need a refresher periodically. And in my studio that can take some time...this from the quilter who regularly compares her cutting table to an archeological dig.

With paper piecing, I need paper piecing paper. Check.

A rotary cutter, ruler, and mat. Check.

A computer and the internet to download the pattern. Yep. I download the patterns from my site. I don't have to go looking. :)

All of that I've got. Handy. Always.

All I require is to be able to reduce the stitch length and the ability to sew on a line. 

That's it. 

And the best part?

They come out perfect. 

Layer your four Center rectangles and using the template you downloaded that corresponds to your chosen Finished Block Size, cut out the patch. The top and bottom of this template will match the cut edges of your cut rectangles.

Use the Template for the CentersRight side up or not, it doesn't matter how these squares are layered because the shape is the same regardless.

With your rotary cutter and ruler, cut away the excess.

Cut the Center patchesThe extra that's cut away is scrap, rarely big enough for anything else.

To cut the correct Side and Side.R (where R stands for 'reversed') patches, for each block we need to stack our 4 cut rectangles so that there are two pairs of RIGHT SIDES TOGETHER layered on top of each other. That's the only tricky thing about this technique. 

With all the edges even, make a small tick mark on the short top edge 5/8" in from the left side. Make the same mark 5/8" in from the right on the bottom short side. (See red arrows)

Mark the side rectanglesIf I'd been smart enough to use a fabric with a definite right and wrong side, it'd be easier to see that I've layered these cut rectangles in two pairs, each RST.

Align a rotary ruler with these top and bottom edges at the tick marks and cut through all four rectangles.

Cut the side rectangles

You have created the 4 pairs of mirror imaged Side and Side.R triangles. We're ready to piece these TiaSs.

Use a tiny dab of Elmer's Washable Glue Stick, goes on purple, dries clear, to hold the Center patch in place between the dashed guidelines, wrong side to the unprinted side of the pattern.

On this translucent vellum, you know when we're looking at the printed side of the pattern because the words and symbols are readable.

Position the center between the guidelinesThe bottom edge of the Center extends roughly a 1/4" past the outside dashed lines. When we trim to perfection, we WANT something to trim.

General Sewing Machine Setup for Paperpiecing

  • Reduce your stitch length to 16–20 stitches per inch (1.3-1.6 mm). This perforates the paper and stabilizes the seam when you remove the pattern. [Learn more about stitch length here.]
  • Reduce your machine's speed or just plain slow down. Sew only as fast as you can stay on the stitching lines.
  • Install an open toe appliqué foot (sometimes called an 'embroidery' or 'satin stitch' foot) if you have one (it's easier to see where you're stitching with one installed). 
  • If your machine has a needle stop up, use it. The stitching goes faster when you don't have to lift the presser foot with every seam.
  • As you stitch each seam, start and stop a generous 1/4” before and after the solid stitching lines. ALWAYS. Future lines of stitching secure the ends.

After adding each patch, press the unit as it was sewn to set the seam and then open. The SA is automatically pressed towards the last patch added.

Before adding the next patch, take a look to make sure the one you just added covers the space plus seam allowance that it is supposed to.

Steam is optional and usually curls the pattern. 

If that bothers you, don't use steam. Sometimes I do. Sometimes I don't.

It truly depends on my mood.

Remember, as you follow this paper piecing tutorial, the printed and the fabric sides of this block are mirror-images of each other.

At last!

Let's sew!

With RST, layer a Side with the Center. The wide end of the Side to the top point of the center.

Because the Sides are a lighter fabric, I've scooched (love the technical quilting term, right?!!!) the generously sized Side patch just a smidge past the cut edge of the Center.

That way the darker fabric won't shadow through the lighter one, AND I won't have to come back with scissors to trim away a bit of the darker Center patch.

Add the first side to the CenterYou can see how I positioned the side just a wee bit past the cut edge of the center patch—a smidge is just a few threads wide.

From the printed side of your pattern, sew the seam starting and ending past the outside edge of the unit.

Sew on the solid lineStitch from the printed side


While I LOVE working with vellum paper, it does have a tendency to curl when pressed. It's the tradeoff for being able to see through the pattern.

Pressing the #1/Side unitI'll put up with the vellum curling, even though it's not my favorite thing.

Sew the second seam just like the first one.

Sewing the second seamYou might be able to make out that I've 'crunched' the vellum a bit to make it lay flatter.

And yes, Virginia, it's possible to chain piece when you're paper piecing.

As long as the seam starts at the outside edge on one side, and ends at the outside on the other, you can chain piece—saving both time and thread!

Chain piecing the last patchYou can chain piece these TiaSs

Give your TiaSs a good press.

At your cutting mat, trim them to perfection. 

My preference is to lay the 1/4" mark on the ruler directly over one line around the inside solid square—that is the finished edge of the TiaS. 

This way, we establish a perfect quarter inch seam allowance. It's also much easier (and more accurate) to line up than trying to match the edge of your ruler with the outside dashed line of the block—the unfinished size.

Trim all four.

Utter perfection. 

Since we precut our paper piecing patches on the straight of grain, you can remove the paper now without fear of stretching any of those edges. 

The finished TiaS just before removing the paper patternNothing, but NOTHING beats the precision of this simple technique!

Return your sewing machine to your everyday settings.

We stitch the remainder of the block with traditional techniques.

Install your favorite quarter inch presser foot. Adjust the needle position if needed. Increase to your normal piecing stitch length.

Step 3: Assemble our Texas quilt block 

Arrange all the units we stitched into the Texas quilt block design. The dark squares in the 4-patches all move from upper right to lower left.

Sew the units in each row together. Use pins to match the seam in the 4-patch with the point of the TiaS. 

Learn more about Pinning for Perfect Points here.

All that's left is to sew the rows together. Use pins as you need them for good matches.

Yippee-ky-yay! Here's our finished Texas quilt block.

That was easy! What can we do with the blocks?

Design a quilt using the Texas quilt block as your inspiration

Blocks with something going on in the corners tend to lead to some very interesting design ideas, and our Texas block is no different. 

But I have to admit. It really blew my skirt up just how intricate some of these beauties are using the simple four-patches, TiaS, and simple sashing.

I think you'll be surprised, too.
