The Scrap Zig Zag Quilt Block

Skill Level: Beginner

The Scrap Zig Zag quilt block is a fun little piece of patchwork—just triangle squares and cut squares and rectangles. No points to match. Simple piecing.

Quick to make, this block would be perfect for your quilting bee's next exchange.

Choose all scraps for either the dark or the light fabric and this little gem will live up to its name.

Let's get to the quilting!

General Instructions

---

All seam allowances are 1/4".

The following abbreviations are used in this tutorial:

• SA - seam allowance(s)

• RST - right sides together

• HST - half square triangle(s)

When you are instructed to press, first press the pieced unit flat to set the seam.

Next, open up the patches and press as instructed.

Step 1: Cut the fabric patches

Sample Size:

Grid: 4x4

Design Type: Pinwheel

Attribution: Kansas City Star

Patches for the triangle squares are cut based on the Quick Pieced method and are denoted by a **.

I prefer to cut these patches a 1/4" larger, stitch and then trim each to the perfect size.

While a darker background fabric is used for the sample block, you can swap lights and darks.

Choose what works best for your quilt.

**I prefer to cut my patches extra large for HST, stitch, and then trim them to size. If you prefer to do the same, add a bit extra to the measurements for Patches #1 and #2 above (I added 3/8" to each dimension for the sample block). There is a chart further down in these instructions where you need it for trimming them to size. If you have a perfectly reliable 1/4" seam allowance use the dimensions in the cutting charts for these patches.

These are the cut patches.

Step 2: Construct the units

Half Square Triangles

Make 4

With a pencil or chalk draw a diagonal line from corner to corner on the back of the lighter of either the t#1 or #2 squares.

With RST, pair a #1 and #2. Stitch a quarter inch from both sides of the drawn line.

Cut along the line to create 4 triangle square units.

Press with the seam allowance towards the darker fabric.

Use the chart below to check that your stitched HST are the correct size. Trim if needed.

HST Dimensions
Finished Block Size	Trim HST to…
4"	1½"
5"	1¾"
6"	2"
8"	2½"
12"	3½"

Stitch the quarters

Make 4

Each quarter of this block is exactly the same.

Sew the #3 square to the #1/#2 half square triangle unit as show below. Press SA toward #3.

Repeat for the three remaining pairs.

To this sewn unit, stitch the #4 rectangle to the side that contains both light and dark patches at the edge.

Press with the seam allowance towards the #4 rectangle.

Repeat for the 3 remaining pairs.

Step 3: Assemble the Scrap Zig Zag Quilt Block

Lay out the sub-units in two rows. Each is rotated a quarter turn as you move clockwise around the block.

Stitch the pairs together into rows like this. Press the SA towards the light rectangle to reduce bulk.

Stitch the rows together. For this block I chose to twirl the seam allowance in the center. From the back it looks like this...

And here is our finished Scrap Zig Zag quilt block from the front.
