The Log Cabin quilt block is one of the most useful classic blocks for learning accurate strip piecing and making good use of fabric scraps.
This free version from American Patchwork & Quilting / AllPeopleQuilt creates a 9-inch finished block with a yellow center, narrow black strips, and colorful orange, pink, and purple “logs” arranged around the center.
The construction uses only straight seams, but the gradually increasing strip lengths make accurate cutting, consistent seam allowances, and careful pressing especially important.
Below you’ll find an overview of the block, fabric-planning ideas, construction tips, layout possibilities, common mistakes to avoid, and a direct link to the official free pattern.

What Is a Log Cabin Quilt Block?
A Log Cabin block begins with a center square and grows outward by adding rectangular fabric strips around that center.
Each new strip is slightly longer than the one before it, creating a stepped spiral or framed effect.
The basic construction is simple, but changing the placement of light, dark, warm, or cool fabrics can produce dramatically different quilt layouts.
About This Free 9-Inch Version
The official American Patchwork & Quilting pattern uses a 3½-inch yellow center square surrounded by 1½-inch-wide strips.
Black print is combined with orange, pink, and purple scraps to create strong contrast as the block grows.
The finished block measures 9 inches square, while the sewn block measures approximately 9½ inches square before being joined into a quilt.
Materials
The official pattern calls for:
- scraps of yellow print,
- orange print scraps,
- pink print scraps,
- purple print scraps,
- and a black print large enough for the required strips.
Because each “log” is fairly narrow, this block is well suited to leftover strips and small pieces from previous projects.
American Patchwork & Quilting provides the exact cutting list, numbered strip positions, block diagrams, and downloadable PDF. Use the official source while sewing rather than relying on a third-party copy of the pattern.
How the Log Cabin Block Is Constructed
Step 1: Start with the Center Square
The featured pattern begins with a yellow 3½-inch square.
This becomes the fixed reference point around which all of the remaining strips are added.
Step 2: Add the First Black Log
Sew the first black rectangle to the center square using a consistent ¼-inch seam allowance.
Press carefully before adding the next strip.
Step 3: Add the Second Black Strip
A second black strip is added to another side of the center unit.
At this stage, the block begins to establish the rotation that will continue through the remaining rounds.
Step 4: Add the Orange Logs
Orange strips are added next, continuing around the center.
Each new rectangle is cut to fit the growing edge of the block.
Step 5: Continue with Black, Pink, and Purple
The remaining strips are added in the numbered order shown in the official assembly diagram.
Black sections alternate visually with the brighter colors, creating the distinctive contrast of this version.
Why Accurate Seam Allowance Matters
Log Cabin blocks contain many seams.
A tiny seam-width difference repeated across several strips can make the finished block noticeably too large, too small, or uneven.
If possible, test your quarter-inch seam before beginning the complete block.
Press After Every Log
Do not wait until the complete block is finished before pressing.
A newly added strip should lie completely flat before the next strip is attached.
The official instructions recommend following the pressing arrows in the diagrams and, where no direction is specified, pressing toward the darker fabric.
Check the Block as It Grows
One useful habit is to check the size and squareness of the unit after several strips have been added.
Catching a small problem early is much easier than correcting a distorted block after all twelve strip positions are complete.
Fabric Ideas for a Log Cabin Block
Scrappy Rainbow
Use a different colorful print for every pair of logs while keeping one consistent dark fabric.
Light and Dark
Divide your fabrics into light and dark groups to create stronger secondary patterns when multiple blocks are joined.
Monochromatic
Try several shades of one color, moving gradually from light to dark.
Low-Volume Background
Replace the black print with cream or low-volume fabrics for a softer version of the design.
Fabric Scrap Version
Use leftover strips from previous quilts rather than coordinating yardage.
Keeping a similar value on each side of the block can still create structure even when every print is different.
Why Log Cabin Blocks Are Great for Scraps
The block grows from narrow strips of several different lengths, so it can use pieces that may be too small for larger traditional blocks.
Sorting scraps by width before you begin can make construction much faster.
For this official version, many of the logs are cut at 1½ inches wide, making narrow leftover strips especially useful.
Log Cabin Quilt Layout Ideas
One Log Cabin block is simple, but repeating the block and rotating it can create much larger secondary patterns.
Before joining finished blocks, try arranging them on a design wall, floor, or large table.
Rotate individual blocks and watch how the darker or brighter sections connect from one block to the next.
Barn-Raising Style Layout
Rotate blocks so the contrasting sections create expanding diamond-like shapes across the quilt.
Diagonal Layout
Align similar values to create strong diagonal movement.
Scrappy Mixed Layout
Rotate blocks more freely for a less formal, highly colorful quilt.
Common Log Cabin Mistakes to Avoid
Attaching a Strip to the Wrong Side
Follow the numbered assembly order and keep the diagram beside your sewing machine.
Skipping Pressing
A strip that is not lying completely flat can affect every strip added after it.
Using an Inconsistent Seam Allowance
Repeated small errors accumulate quickly in a Log Cabin block.
Stretching Long Narrow Strips
Let the feed dogs move the fabrics through the sewing machine naturally.
Trimming Without Checking the Pattern
This version uses specific strip lengths. Follow the official cutting chart rather than trimming every strip by eye.
