Block B Assembly - Step 4 St. Paddy's Field QAL

Step 3: Assemble Block B

Now that your four-patch units are complete, it’s time to combine them to create Block B.

Each Block B uses 4 four-patch units. PDF Instructions

1. Lay Out Your Units

Place the four four-patch units on your design surface in a 2 × 2 grid.

Rotate the units so the dark green squares form a diagonal line running from the upper right to the lower left of the block as shown in the picture above.

Your layout should look like this:

Top Row

• Four-patch with dark green in the upper right

Bottom Row

• Four-patch with dark green in the lower left

Take a moment to double-check the orientation before sewing.

---

2. Sew the Rows Click here for Video Tutorial on Block B Assembly

1. Sew the top two units together.

2. Sew the bottom two units together.

Use a ¼" seam allowance.

Press the seams in the rows toward the darker green squares if possible.

---

3. Spin the Center Seams

To reduce bulk in the center:

1. On the back of each row, gently loosen the stitching at the seam intersection.

2. Spin the center seam so the seam allowances rotate in a circular direction.

This creates a small four-patch “pinwheel” seam on the back and allows the block to lay flatter.

---

4. Join the Rows

1. Place the two rows right sides together.

2. Nest the center seams so the intersections lock together.

3. Sew across the center using a ¼" seam.

Spin the center Seam and Press, Refer to video linked above for visual instructions

5. Check Your Block 

Your finished Block B should measure the unfinished size 8.5"square and show the diagonal chain of dark green squares across the block.

Come Quilt Along - St. Paddy's Field

Let's Skip though St. Paddy's Field together! In this quilt along we will be making the quilt shown in the picture above. Beginner Friendly! Honest!

This year's Kona Cotton Color for 2026 is called Wander. It is a calm, confident Green that invites curiosity and open ended possibility! You do not have to make this quilt in Green. I will be making two colorways as we move through this quilt. It lends itself to scrappy (which I love). Fabric requirements will be listed here today to give you time to gather your bits and bobs.

The quilt will finish at 64.5" x 64.5". You can elect to make a table runner, a baby quilt, a larger quilt by simply increasing or decreasing the number of blocks you make. Your choice! This quilt is very suitable for a beginner quilter and will also provide a base for a more advanced quilter who may wish to experiment a bit.

Okay! Let's get down to business here. You will need the following fabrics:

For a scrappy look you will need:

11 Fat Quarters of low volume for your backgrounds

9 Fat Quarters of your main color (the dark green in the photo)

3 Fat Quarters of your secondary color (the light green in the photo)

You can also use your scraps in any combination that will equal those quantities listed above.

If you are using Yardage, you will need:

3 3/4 yards of your background fabric

3 yards of your main color

3/8 yard of your secondary color

1/2 yard of binding color

So Gather your fabrics, mark your calendars, we will meet here again on February 19th for cutting  instructions. 

This quilt will be chain pieced and will go quickly. We should have fun!

Sunday, February 15, I will post up some fat quarter bundles in our Etsy Shop if you are needing a selection. They will be $2.00/fat quarter in a bundle of 5 for $10.00 and as always, if you order $30. or more your shipping will be free!
