What is a 4-Patch Quilt Block?

The 4-patch quilt block consists of four smaller fabric squares sewn together in a simple two-by-two grid. It’s a basic block that’s easy to assemble but offers endless opportunities for creativity through fabric choices and color placement.

Quick to make: Perfect for fast quilts or to use as fillers between more complex blocks.
Flexible design: Great for scrappy quilts, planned patterns, or even modern quilt designs.

Materials You Need to Make a 4-Patch Quilt Block

Fabric in two contrasting colors or patterns
Rotary cutter and cutting mat
Quilting ruler
Sewing machine and thread
Iron and ironing board

Make sure to select fabrics that provide a nice contrast to emphasize the grid layout of the block. Using a combination of solids and prints works well for visual interest.

Step-by-Step: How to Make a 4-Patch Quilt Block

Cut Your Fabric
Start by cutting two fabric squares. For a standard 4-patch block, cut your squares to 3” each, resulting in a 4.5” unfinished block. This size is perfect for quilts that feature multiple smaller blocks.
Sew the Pairs
Place two squares of contrasting fabrics right sides together, and sew along one edge using a ¼” seam allowance. Press the seams toward the darker fabric.
Join the Sewn Squares
Take the two sewn squares and lay them out with their seams opposite each other, creating a checkerboard effect. Nest the seams, pin them, and sew the two halves together using a ¼” seam allowance. Press your seams open or to one side.

The Perfect Leader and Ender Project

If you’re familiar with leaders and enders, you’ll know that the 4-patch block is ideal for this technique. Leaders and enders allow you to sew pieces between other projects, using scraps or extra fabric to make separate quilt blocks as you work on a primary quilt.

Using a 4-patch block as a leader and ender project is an excellent way to work on multiple quilts at once without wasting thread or time. As you sew your main quilt, feed 4-patch units through your machine as leaders and enders, and by the time your main quilt is finished, you’ll have a stack of 4-patch blocks ready to go!

Tips for Perfect Quilt Blocks

Consistent Seam Allowance: A precise ¼” seam allowance ensures that your blocks come out square and the correct size.
Pressing Seams: Press your seams carefully—pressing them to the side helps with nesting, while pressing them open can reduce bulk at the intersections.
Chain Piecing: When making multiple 4-patch blocks, chain piecing saves time and makes the process more efficient. Sew all your blocks at once by continuously feeding fabric squares through your machine.

Creative Uses

The 4-patch quilt block might be simple, but it’s incredibly versatile. Here are a few ideas for incorporating it into your quilting projects.

Scrappy Quilts: Gather up your fabric scraps and make a vibrant scrappy quilt filled with colorful 4-patch blocks.
Borders and Sashing: Use 4-patch blocks as a decorative border or as sashing between larger blocks in a quilt.
Combined with Other Blocks: Pair 4-patch blocks with half-square triangles, flying geese, or 9-patch blocks to create more complex designs.
Substitute Half-Square Triangles for a Twist: Want to give your 4-patch block a fresh look? Substitute half-square triangles (HSTs) for some of the squares in the 4-patch. This simple modification can dramatically change the overall design, adding dynamic movement and texture to your quilt. It’s an easy way to elevate a basic block into something more unique!
