It's time to cut up and sew!

General Instructions

Several abbreviations are used on this page. They are:

  • SA - seam allowance
  • RST - right sides together
  • HRT - half rectangle triangles
  • TiaS - triangle in a square

1/4" SA are used through this tutorial. 

Highlighted in yellow, pressing instructions are easy to spot.

To press, first press the patches in the closed position 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.

My personal preference is for a super-easy paper to tear away—less stress on the stitches.

Subcutting patches

We need mirror image patches for both the HRTs and TiaS units.

Layer your background #1 and Side patches RST. Layer your dark #2 patches RST. This is what creates the mirror image patches when you cut.

With both groups of patches oriented with the short edges on the top and bottom, make a mark at the edge, 5/8" in from the top left and 5/8" in from the bottom right.

Line up your ruler with these marks at the top and bottom edges and cut in half with your rotary cutter.

Below, the stack of #2 patches has been cut in half.

Subcut the #2 patches for your HRTs

For the TiaS, the patches can be right side up or down—it doesn't matter. Lay the Center template on top of the four rectangles. The top and bottom edges of the template should match the edges of your Centers. 

Use your rotary cutter to remove the excess from both sides.

Step 2: Assemble the patches for a Dervish Star

All the sewn units in this block are paper pieced for speed and accuracy. The first thing to do is set up our sewing machine.

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. It also stabilizes the seam when you remove the pattern. [Learn more about stitch length here.]
  • Reduce your machine's speed or just plain slow down when you stitch. 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!

Triangle in a Square Unit (TiaS)

Make 4     

Triangle in a Square or TiaS unit

Use just a wee bit of Elmer's Washable Glue Stick to hold the backside of the Center patch in place on the unprinted side of the TiaS pattern.

The dashed guidelines make this quick and easy to do accurately.

Position the Center patchThe red arrows point to the patch that's glued to the unprinted side of the pattern

With RST align the long bias edge of a Side with the Center. If your background is light like mine, nudge the Side a couple of threads past the edge of the Center. 

This will prevent the darker fabric from shadowing through the lighter one.

Position the first Side

Sew on the solid line starting and ending past the outside edge of the TiaS as shown below.

The stitches should extend past the beginning and end of the seam, past the outside edges of the unitThe stitches should extend past the beginning and end of the seam, past the outside edges of the unit

Press.

Add the second Side just as you did the first one.

Position the opposite side

Press.

Here is an untrimmed versus a trimmed unit.

Untrimmed versus a trimmed Triangle in a Square unitUntrimmed (left) and trimmed to the perfect size (right)

To trim, line up the 1/4" line on your ruler (red arrow) with one side of the solid square.

Cut away the excess with your rotary cutter. (I find it so much easier to match the 1/4" with the solid line than the edge of my ruler with the outside dashes.)

Trimming one side on the TiaSTrimming the first side of a sewn TiaS—3 more to go!

After trimming is complete, we've got four accurate TiaSs with all the points and angles exactly where they need to be.

Our four TiaS are ready to be pieced into the block

Half Rectangle Triangle (HRT) Units

Make 4 ea, A and B units      

The 'A' and 'B' Half Rectangle Triangle or HRT unitsThese images are shown from the fabric side.

When you look at the printed pattern as compared to the illustration above, you'll notice they are the mirror image of each other. We've taken this into account as we cut our patches. (Remember we subcut those rectangles in pairs right sides together.)

Use the Elmer's Glue Stick (with a light touch) to stick the backside of the correct #1 patch to the unprinted side of the patterns. Use that dashed line for quick placement. 

The #1 patch is in the correct positionYou can just make out the shadow of the patch, properly positioned on the unprinted side of this pattern

With RST, align the long bias edge of a #2 with #1. 

If you are new to making HRTs, fold back the patch before stitching to check that you've used the correct patch. For HRTs it's always narrow edge to wide one.

Postion #2 over #1 with RST

The seam runs from clear across the unit. That means we can chain piece all eight HRTs to save a bit of time.

Trim these HRTs to size the same way we did the TiaS.

Below are the pairs of 'Bs' (left) and 'As' (right), untrimmed versus trimmed.

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.

At this point, I remove all the paper, it's so much easier to stitch units together without it.

A lot less lumpy, too.

Remember, by precutting and then carefully subcutting our patches, all the outside edges of our TiaSs and HRTs are on the stable straight of grain. There is no bias to stretch out of shape.

The paper no longer serves a purpose. Get rid of it! :D

Sides

Make 4     

If we've done a good job stitching directly on the line (especially where the it hits an outisde edge), these units will practically sew themselves together.

That is the beauty of paper piecing. The stitching is mindless, the trimming straightforward, and the results are accurate.

With RST, sew an 'A' HRT to the left side of and TiaS and a 'B' HRT to the right.

Pin to hold all the edges together. 

If your stitching wasn't quite up to your usual accuracy, have a look at this article on Pinning for Perfect Points.

Sew an HRT-A and an HRT-B to each side of a TiaS

These seams are pressed away from the TiaS.

They can be a bit lumpy. To smush ( quite the technical quilting term, eh? :D ) the lumpiness, use my 'secret pressing technique'. Simple to do.

Unbelievable results.

Step 3: Assemble your Dervish Star quilt block

Arrange the stitched and cut patches into the Dervish Star design. Cut #3 squares in the four corners. A big luscious hunk of a yummy print in the center and the background side of the 'Sides' towards the outside edge.

All the cut and pieced units arranged in to the Dervish Star design

With RST, sew the units in each row together.

SAs are pressed away from the Side units in each row.

The units sewn into rows

Stitch the last two seams to complete your Dervish Star quilt block.

The seams at the corners nest. Use pins to keep them together as you sew and keep those edges even.

My favorite 1/4" foot has a flange on the right-hand side. As long as your pins don't hang over the edge, they don't get in the way while sewing.

Sewing the pinned rows together

And here's our finished Dervish Star quilt block. Paper piecing makes all those pointy points easy to piece. Add them to a standout print, and you've got a smashing quilt block.

What happens when a Dervish Star is set on point?

Any time you see half rectangle triangles used as star points, you just KNOW that there's something good in store for you when the block is set on point. 

Our Dervish Star quilt block doesn't disappoint.
