Everything You Need to Know About 4 Patch Quilt Blocks
If you’ve been searching online for info on 4 patch quilt blocks, you’ve come to the right place. As an avid quilter with over a decade of experience, I’ve made dozens of quilts using various block patterns – and the 4 patch is one of my favorites. In this article, I’ll cover all the basics on 4 patch blocks as well as some tips and tricks I’ve picked up along the way. By the end, you’ll have a solid understanding of how to plan, cut, piece and assemble these simple yet versatile blocks.
What is a 4 Patch Quilt Block?
Put simply, a 4 patch block is made up of four squares sewn together. Kind of like the name implies, right? Basically, you take two different fabrics and cut them into squares. Then you sew the squares together in a 2×2 grid pattern. Boom, you’ve got yourself a 4 patch! Sounds easy enough, but as with any quilt block, the devil’s in the details. Let me break it down step-by-step.
Planning Your 4 Patch Block
The first step is selecting your fabrics. You’ll need two different print fabrics to make each 4 patch block – one for the top two squares and one for the bottom two. Pro tip: pick fabrics that contrast well in color and scale. Avoid fabrics that are too similar or they may blend together once pieced. From my experience, bold prints paired with tone-on-tons work well.
Next up is cutting your fabric. For standard 4 patch blocks, aim to cut your squares around 2.5-3 inches. This allows for seam allowances so your finished blocks will be closer to 2 inches. You’ll need two squares of fabric A and two squares of fabric B for each block. Cut with care – squaring up your cuts is key for accurate piecing later on.
Piecing the 4 Patch Block
Now for the fun part – sewing those squares together! Place one square of fabric A right sides facing up on your work surface. Then place a square of fabric B on top, right sides facing down, aligning the edges. Kind of like a sandwich! Sew around the perimeter with a 1/4 inch seam allowance. Go slowly, backstitching at the beginning and end for a secure seam.

Once stitched, flip the top fabric B square open and press the seam toward the darker fabric with an iron. This will help everything lies flat. Repeat to add the remaining A and B squares, pressing the seams in opposite directions so they nest together nicely. Congrats, you’ve just made your first 4 patch block!
Tips for Perfect 4 Patch Blocks
Now that you know the basics, here are some tricks I’ve learned over the years to ensure picture-perfect 4 patch blocks every time:
- Use a 1/4 inch foot on your sewing machine for precise seams.
- Always press seams as you go to avoid bulk later on. I like pressing to the darker fabric.
- Trim your blocks to a consistent size (2 1/2 inches) before assembling the quilt top.
- Stitch with the Fabrics right sides together for a perfectly flat finish.
- Pile unfinished blocks together for easy piecing in front of the TV ๐บ
Paying attention to those fine details will make your life much easier once it comes time to assemble the full quilt top. Trust me, I’ve totally been there trying to piece together wonky blocks before.
Putting It All Together
Alright, so now you’ve got a stash of perfectly pieced 4 patch blocks. Time to join them into a quilt top! There are a ton of layout options – grids, diagonals, random. Play around and see what you like best. I kinda dig the ranDOM look myself sometimes, helps disguise any imperfect blocks.
Once you’ve arranged the blocks, join them into rows by stitching block to block. Press seams open or to the side, your preference. Then stitch the rows together to complete the quilt top. At this point you’d add batting and backing before quilting and binding to finish. But that’s a topic for another day!

Final Thoughts
In summary, 4 patch blocks are simple to make but so versatile. You can incorporate all kinds of prints, colors and designs. They also piece together quickly to make nice, cozy quilts. Whether you’re new to quilting or a seasoned pro, give these easy blocks a try. You might be surprised by how much fun and satisfaction you get from creating something with just four little squares. Kind of makes you appreciate the little things in life, you know?
