The Log Cabin quilt block is perhaps the most well-known, best loved of all quilt designs. Simple enough for a beginner quilter to confidently stitch...
...yet versatile enough to pique the interest of a more experienced quilter.
The basic structure of this quilt block is a center shape surrounded by strips, or 'logs'.
While square blocks typically come to mind, log cabin blocks can be square, rectangular, triangular, diamond shaped, twisted or even curved. The starting shape can be centered or anywhere else in the block.
The standard log cabin block is constructed by adding strips (the logs) one at a time around a centered square.
In this tutorial you'll find:
Several common abbreviations are used in this tutorial:
'Logs' is another name for 'patches'. Since we're talking about a Log Cabin block, the word seems only fitting!
SA are all 1/4".
I prefer to prewash and starch my quilt fabric before cutting.
In my humble opinion, the cutting and sewing are both more accurate when using starched fabric. The downside is that you'll need to wash the quilt after it's finished to completely remove the starch.
We're not having to beat the crap out of our quilt on a rock at the stream. We simply throw it in the washing machine and turn the knob.
To further improve the accuracy of my Log Cabin blocks, I cut all my rectangular patches with the long edge on the lengthwise grain (parallel to the selvedge).
Lengthwise grain has far less stretch than cross grain patches. That means you won't accidentally stretch your units out of shape as you stitch. Learn more about grainline here.
Finally, I do a sewing test with scraps from the fabrics I'll use in my quilt. A perfect seam allowance is a beautiful thing!

Our Log Cabin block has a center square surrounded by five 'rounds' of logs.
In the picture to the right, round is colored in a unique hue that includes both light and dark values to represent the opposite sides of the block.
For the Patch names in the chart below the number refers to the 'round', so all Patch names that start with 1 are in the first round of logs.
The letter—a, b, c or d—refers to the order of piecing.
Cut one of each patch for each block you make. So if you have a design with 40 blocks, cut 40 Centers, 40 1a, 40 1b, etc.
The sample in this tutorial is constructed with like pairs of dark logs. 5 different purple fabrics are used where 1c/1d is one fabric, 2c/2d is another, etc.) and a single light fabric.
You, of course, are free to use any combination of fabrics. Choose what makes YOUR heart sing!
The only 'rule' to follow is there should be a clear difference between your light and dark fabric values.
The stepped diagonal line created by the piecing should be strong and easy to distinguish.

The cutting chart below is for strip widths that finish at 1", 1-1/4" and 1-1/2". This results in blocks with finished sizes of 11", 13-3/4" and 16-1/2" respectively.
Below are all the patches, stacked one on top of the other.
It's easy to see that for our 11" finished sample block, each patch is 1" longer than the previous one. Instead of a traditional red center, I've chosen to use a shade of violet.
If I'm making a single block, I like to keep my patches stacked this way to keep things organized.
If I'm making loads of blocks, then I'll sort out the pairs of lights and pairs of darks by round.
You might choose to label the patches instead. Do what works best for how YOU work.
