Quarter Square Triangle Pouch Tutorial

Quarter Square Triangle Pouch


Hello from chilly Canada! My country has varying degrees of winter but where I am (smack dab in the middle with no mountains to insulate me) it's full-on winter. The gloomy days threaten to steal my sew-jo but I try to combat the dreariness by learning new techniques. I've been interested in making quarter square triangles and when I learned that I didn't have to make a half square triangle first (my nemesis) I was thrilled! I designed a zakka inspired pouch to incorporate the blocks and added darts on the bottom to give the pouch some depth. I hope you'll make some too, let's get to the tutorial!


You may gift finished items, but please do not sell items made from this pattern!


Skill Level: Intermediate. Zipper installation experience is needed.

Seam Allowance: 1/4 inch thoughout. Baste and Topstitch with 1/8 seam allowance.

Finished Size: 8.5" Wide x 5.5" Tall

Supply List:

- Four Fabrics, I used a variety of fabrics to give it more of a patchwork feel. Quilting Cotton or Linen work best. I used:  Wisteria/Navy Stripe/Pure White/Soft Mustard(Linen)

9 inch nylon zipper Dailylike 9" zipper in white

Lightweight Fusible Fleece, I used: 2 oz Iron-on Fleece

3/4 inch D ring (optional)

Embroidery Floss (optional)

Make The Dart Template:

Using a piece of letter size paper or preferrably cardstock, cut out a rectangle that measures 9.5 inches wide by 3 inches tall. 

With a small plate or roll of ribbon, draw a curve on the bottom right corner. Cut out the curve.

Now fold the top right corner down so it meets up with the bottom.

With a ruler, make a mark 1/4 of an inch to the bottom left of the fold and another one 7/8 of an inch up from the bottom of the fold. Connect those marks. Now cut out that half triangle and unfold. Congrats, you just made your first dart! 

 To complete the template, fold it in half and trace your curve and dart on the left side and cut it out. Now your template is done! 


Prep your Fabric:

From your Exterior Fabric cut:

1 piece 9.5 inches wide x 3 inches tall (Bottom Panel)

1 Piece 9.5 inches wide x 7 inches tall (Back Panel)

*use your template to trace the curved edges and darts onto your fabric. Cut around the curves and cut out the darts.

From your Lining Fabric cut:

2 pieces 9.5 inches wide x 6.75 inches tall

*use your template to trace the curved edges and darts onto your fabric. Cut around the curves and cut out the darts.

From your Accent Fabrics (Q.S.T Panel):

2- 4.25 inch squares from the white fabric

2- 4.25 inch squares from your print fabric

2- 2 inch squares for the zipper tabs

1- 2.5 inch square for the D ring tab (optional)

From your Striped Fabric cut:

1- 9.5 inches wide x 1.5 inches tall

-Fusible fleece/Lightweight Interfacing: 2 pieces 9.5 inches wide by 7 inches tall (use your template to curve the bottoms and cut out the darts)

Making the QST Panel:

Using the 45 degree angle on your ruler, draw an 'X' on both of your white fabric squares. Place on the right side of your printed fabric with the 'X' facing you. 

 Along both sides of only ONE line, sew with a 1/4" seam allowance. Now cut the fabric on both of the lines. Open your triangular shaped pieces and with a hot iron, press the seam to the printed side of the fabric.

Arrange your triangles so that the printed fabric meets in the middle in an hour glass shape. Place them right sides together. The seams will nicely 'nest'. Sew the two triangles together. Repeat with two other pairs. Press the seam open.

*Note: You will have two extra triangle pieces, you can set them aside for another project.

Cut off the little ears that hang over the blocks. Now you can arrrange the three blocks in whichever design you choose. Sew the three blocks together. Press the seams open. 

Assembling The Exterior:

Take your bottom panel with the darts and place it right sides together along the bottom of your QST panel. Sew. Press the seam toward the bottom.

Now place your top accent piece right sides together along the top of the QST panel. Sew. Press the seam toward the top. 

Now fuse the interfacing to the wrong side of the exterior pieces.

*At this stage you can add some hand stitching around the blocks. I used some embroidery floss and outlined the white fabric with some running stitches. 

Zipper Installation:

Cut the ends off your 9" zipper just after the metal stops at each end. Refer to the picture. Now take your 2 inch squares of fabric and fold them in half, press with an iron. Open and fold in the edges to the fold line, press, fold again. Slid over the ends of the zipper and topstitch them in place. Cut off the overhang so they are flush with zipper. 

Place an exterior piece right side up on your table. Center the zipper right side down on the fabric. There should be a little over a 1/4" space on each end of the fabric

Place the lining fabric right side down on top of the zipper. The zipper should now be sandwiched between the exterior and lining fabric. Sew in place. Repeat for the other pieces.

Press your exterior and lining away from the zipper and topstitch the fabric along the zipper. 


Optional D-Ring:

Fold your 2.5 inch square of fabric in half and press. Open and fold in the edges to the center crease, fold again along the center. Topstitch along both edges of the rectangle. Slid a D ring on and fold the rectangle in half. Refer to the picture for tab placement and baste in place. 


Finishing the pouch:

Now it's time to sew your darts! Simply fold them in half right sides together and sew with a 1/4 inch seam allowance, making sure to back stitch at the beginning and end. 

Unzip your zipper about halfway. Pin your exterior and lining pieces right sides together. Match up the darts and have their seams facing in opposite directions for smoother sewing.  Leave a 2.5 inch opening at the bottom of the lining. 

Your final step is to sew around the perimeter of the pouch. Be sure to backstitch at the beginning and end.  Clip notches or use pinking shears/rotary cutter around the curves for smooth seams.

Turn it right side out through the opening in the lining. Slipstitch or topstitch the opening closed and tuck the lining back inside the pouch. Give it a good press and your pouch is done!

Perfect for holding a few essentials and the darts give it some depth to stuff it with all your goodies! Please tag me on Instagram and use the hashtag #qstpouch if you make some!
