Let's make our Broken Sugar Bowl!

General Instructions

Several abbreviations are used on this page:

SA - seam allowance
HST - half square triangle
RST - right sides together

All SA are 1/4" unless otherwise noted.

Step 1: Cutting

Choose a medium and dark fabric with enough contrast so that the individual pieces are clearly differentiated.

I prefer to cut over-sized patches for my half square triangles, then sew the unit and trim to the correct dimensions.

In this tutorial for the 6" finished sample block, I cut my #2 and #3 patches 3-1/8" x 3-1/8" instead of the 2-7/8" x 2-7/8" listed in the chart below—adding 1/4" to each dimension—for specifically that reason.

If you'd like to cut your HST patches oversized, they are marked with ** below.

Step 2: Create the Broken Sugar Bowl units

Half Square Triangles (HST)

Make 4

We'll use the Quick Pieced Method for making these HSTs.

Draw a diagonal line on the back of both #3 background squares.

Stitch a 1/4" from both sides of this drawn line.

Stitch on both sides of the line to create the HST units

After stitching, give the pairs a quick press as they were sewn and then cut them in half on the drawn line.

Cut each pair of squares in half on the drawn line

Press the four HST open with the SA to the dark.

Find your Finished Block Size in the chart below and trim your HST as directed. If you cut generously you'll be trimming more than if you cut the patches the exactly as listed in the Cutting Chart.

Finished Block Size	Trim HST to...
6”	2-1/2”
9”	3-1/2”
12”	4-1/2”

Four Patches

Make 1

Make 2

With RST, sew the #4 and #5 strip together along the long edge.

The SA is pressed to the dark.

Find your Finished Block Size in the chart below.

Verify that your strip set measures true to the corresponding width. Subcut the stripset into four equal units the 'Subcut Width'.

Finished Block Size	Stripset Width after Stitching	Subcut Width
6”	2-1/2”	1-1/2”
9”	3-1/2”	2”
12”	4-1/2”	2-1/2”

With RST stitch a #6 to a #7 square. Repeat for a total of two.

Press the SA toward the darker fabric.

Arrange the pairs as shown below.

With RST, sew each pair together. The SA can be pressed to one side or 'twirled'.

These are our finished four patches.

Step 3: Assemble the Broken Sugar Bowl quilt block

Arrange all the units into rows as shown below. The dark #1(large) and #4(small) squares are in the outside corners.

With RST, stitch the units in each row together. Take a quick peek and flip open the patches right before sewing them. It's real easy to mix them up at the sewing machine. When you're sure they're in the proper position, stitch.

Press the SA away from the HST.

With RST, stitch the rows together. I pin to keep the points of the HST matching up where they should be.

And this is the finished Broken Sugar Bowl quilt block!
