The Log Cabin Quilt Block is one of the most recognizable quilt blocks in quilting history. Built one strip at a time around a centre square, it’s a beginner-friendly design that creates bold movement and endless layout possibilities.
The Log Cabin quilt block is one of those foundational blocks every quilter should know. It’s structured, forgiving, visually striking, and perfect for learning accurate strip piecing. Whether you’re brand new to quilting or looking for a classic block to build into a full quilt pattern, this one belongs in your toolbox.
This version of the Log Cabin quilt block is made using traditional strip piecing around a centre square. Strips (or “logs”) are added in a consistent order, building the block outward in a spiral. No templates. No complicated math. Just straight seams and thoughtful colour placement.
If you’re new to quilting, this block helps you practice consistent ¼” seams and precise trimming as you go. If you’re more experienced, it’s perfect for scrappy quilts, light and dark layouts, or dramatic colour play.

Supplies for the Log Cabin Quilt Block
Let’s start, as always, with choosing our fabrics. For this 12-inch Log Cabin quilt block, you’ll need a centre square along with light and dark fabrics to create that classic contrast. This block is perfect for scraps, Fat Eighths, or Fat Quarters – just be sure your light and dark fabrics have strong value contrast so the layout really stands out.
For a beautiful selection of coordinating prints, you can browse current collections at the Fat Quarter Shop!
Here is a list of basic quilting supplies that you’ll need for this project:
- Rotary cutter and self-healing mat
- Quilting Ruler
- Sewing machine
- Thread
- Iron and ironing board or pressing mat
- Pins or clips
- Fabric marker – You can use a marker to keep all of your strips organized. Just be sure it isn’t a permanent marker!
- Spray starch – I prefer to starch my fabrics to help keep things crisp, but this is optional.
Log Cabin Quilt Block Cutting Instructions (12″ Finished Block)
To make one 12″ finished Log Cabin quilt block, you will need to cut:
Centre Square: 3 ½” x 3 ½”
Light Fabrics:
- (A): 2″ x 3 ½”
- (B): 2″ x 5″
- (E): 2″ x 6 ½”
- (F): 2″ x 8″
- (I): 2″ x 9 ½”
- (J): 2″ x 11″
Dark Fabrics:
- (C): 2″ x 5″
- (D): 2″ x 6 ½”
- (G): 2 ” x 8″
- (H): 2″ x 9 ½”
- (K): 2″ x 11″
- (L): 2″ x 12 ½”
Be sure to label your strips. This will make the sewing so much easier!
Step 1: The Centre Square
Place your 3 ½” centre square right side up. This square is meant to represent the “heart” of the block. Traditionally, it was red, but you can absolutely choose any colour you love.
You can also get a little fancy and “fussy cut” a particular design for the centre of your Log Cabin. Just pay attention to the layout if this design is directional.
I like to stack my strips in Letter (or Number) order when I take them to the machine. Then I just keep spinning the block counter-clockwise and add the next strip on the pile.
Step 2: Start Adding Logs
Take strip (A) and sew it to one side of the centre square using a ¼” seam.
Press your seam open or away from the centre.
Next, add strip (B) to the long side of the unit you have just sewn, as shown here.
Again, press your seam open or away from the centre.

Step 3: Continue Building the Block
Continue adding strips in a consistent counter-clockwise rotation, taking note of the letters marked on the strips.
Each time you add a strip:
- Sew with a ¼″ seam allowance
- Press the seam open or outward
- Trim the strip even with the block edges
Alternate light and dark strips as you build outward. The block will gradually grow in size with each round.
Step 4: Square Up the Block
Once your final log (strip L) is added, trim and press the block.
Square your block to 12 ½” x 12 ½”. It will finish at 12″ when sewn into a quilt.
Beginner Tips for Success with the Log Cabin Quilt Block
As with all quilting, accuracy matters. Because this block builds outward, small seam allowance inconsistencies can multiply as you go.
Press as you go. I prefer pressing seams away from the centre to reduce bulk around smaller pieces.
Stay organized. Keep your light and dark strips in clearly marked piles to avoid mixing up your sizes. This is especially important if you are making several blocks at once and chaining them together.
Trim as needed. Don’t wait until the very end if something looks slightly off – small trims along the way help keep the block square.
Giving your block a trim after each strip keeps it nice and square as you go!
Scrap-friendly. This block works beautifully with scraps, as long as strip widths stay consistent.
Common Log Cabin Mistakes to Avoid
Be sure that you are cutting your strips equally. Every log must be cut the same width to keep the block balanced.
Forgetting to rotate consistently. Always add strips in the same directional pattern.
Not checking size as you build. Measure occasionally to ensure your block is growing evenly.
Mixing light and dark placement unintentionally. This dramatically affects final layout results.
