General Instructions

If you need help printing this page, you'll find it here.

Several abbreviations are used on this page. They are:

SA - seam allowance
RST - right sides together
TiaS - triangle in a square
Bac - background fabric

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 paper piecing pattern

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 a total of 4 TiaSs. Then print a copy of the Center template.

Print the Triangle in a Square Paper Piecing Units
Sun Rays Finished Size	# of copies per block	Finished TiaS Size	Center Templates

✂️ Cut your patches for a Sun Rays quilt block

The Sun Rays quilt block

Sample Block Size: 4½" finished / 5" unfinished

Grid: 6x6

Attribution: Kansas City Star

Design Type: Even 9-patch | Star

Please label all your patches. We use their numbers throughout this tutorial.

You'll notice I've swapped the lights and darks in this block. You are always in charge of the fabrics you choose for your quilts—regardless of what the instructions say. :D

Helpful Tip

I took a risk using a dotted background fabric with a 'Rays' fabric that almost matches the dot color. Occasionally, you'll lose the points because the tips are the same color as something in the background fabric.

'Not sure if this will be a problem for your quilt? Make a sample block to be sure.

Subcutting your patches

After cutting out the corresponding Center template, align its top and bottom edges with the top and bottom of your Center fabric rectangles. Right-side or wrong-side up doesn't matter for this patch.

Trim away the excess on both sides with your rotary cutter and ruler.

To cut the mirror-imaged pairs we need, layer your Side rectangles in pairs right sides together. Unlike the triangles we just cut, RST matters here.

The longer edges are on the left and right sides, shorter on the top and bottom.

With a pencil, make a mark 5/8" in from the top left and bottom right edges (red arrows).

Match your ruler with the marks at the edge of the rectangles and cut through all four layers.

After cutting the Side rectangles in half

Precutting our oversized patches like this means that all the outside edges of our units are on the straight of grain—just like if we pieced these with traditional methods.

🪡 Assemble the units for a Sun Rays block

TiaS Unit

Make 4

You'll be sun-stoppable using this paper piecing technique for making your points the pointiest!

To begin, use a tiny bit of a washable glue stick to stick the Center patch, wrong side to the unprinted side of the pattern. I love Elmer's Washable Glue Stick for this—it's cheap, easy to find and works perfectly

Notice below that I've just done a rough cut around the pattern. There's no bonus points for cutting exactly on the line. ;)

The dashed placement lines make it quick work to position the Center.

We need to make a few adjustments to our sewing machine settings to paper piece.

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 and stay on the solid stitching line.

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).

Use a larger needle (90/14) IF you have problems removing the pattern. Personally, I use an 80/12 Microtex Sharp for paper piecing without any problems.

With RST, match the long bias edge of a Side (you can start with either Side or Side.R, it makes no difference) to the Center patch. Wide end to the point or short end.

Just a wee bit of the Center should stick out past the short end of the Side as shown below on the right.

If you're making your TiaS with a dark center and light Sides, nudge the Side just a few threads past the edge of the Center. This will prevent the darker fabric from shadowing through the quilt top later on.

Nudge the lighter Side patch a couple of threads past the edge of the darker Center

For a good sturdy seam, start and end your stitching past the outside dashed edges of the block. No need to trim just yet. The final trim takes care of all the thread tails.

Press.

Add the second Side in the same manner.

Sew the second Side onto the other side of the Center

The stitches go past the beginning and end of the solid line

Press.

Even though I positioned the second Side a bit low, cutting generously sized patches helps. There's just enough to trim away on this one. No ripping for me today!

To trim this to the exact size, at your cutting mat printed side up, line up the 1/4" mark on your ruler with one side of the solid square (red arrow). Trim away the excess.

Repeat for the remaining sides on the remaining units.

All done! These will be easy to piece into our Sun Rays block.

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. Return to your normal piecing stitch length.

🧩 Assemble your Sun Rays quilt block

Arranged the pieced TiaSs and the cut squares into the Sun Rays design. The background fabric is on all the outside edges.

Arrange all the patches into the block design

With RST, sew the units in each row together. I prefer to sew with the pieced patch on top whenever possible. When you can see the seams, it's harder to accidentally flip them over as you stitch.

The SAs are pressed away from the TiaSs to reduce bulk.

Sew the rows together.

With the naked eye, you can see one of the benefits of paper piecing.

As long as you stitch directly on the line—and especially where the stitching line hits the outside solid square—your blocks are SUPER accurate. The points of the triangle in the middle row are EXACTLY where they need to be without any special futzing around.

Perfectly sized units making putting the block together a more enjoyable experience.

These last two seams are pressed out from the center.

I always like to share a look-see from the backside.

When I learned to sew from my Mom and Grandma, they always insisted (painfully sew sometimes!) that the inside of a garment should look as good as the outside. That idea has stayed with me through quilting.
