Lucky 4-Leaf Afghan Block by Margaret MacInnis is a striking knitted square built around four textured leaf shapes that meet in the center to create a four-leaf-clover effect.
Unlike a traditional blanket square worked back and forth from one edge to the other, this design is knitted from the center outward. The construction creates the four leaves as part of one continuous block, so you do not have to knit four separate leaves and sew them together.
The finished block measures approximately 12 inches square and the pattern is currently available as a free download.

A Knitted Four-Leaf Clover Block
The feature that immediately distinguishes this afghan block is the four-leaf motif formed across the center of the square.
Each leaf grows outward as the block expands, creating a symmetrical design that resembles a four-leaf clover.
Because the motif is created through the knitted structure rather than simply added afterward, texture and shaping become an important part of the finished appearance.
Inspired by Traditional Counterpane Knitting
Margaret MacInnis explains that the basic block has roots in an antique counterpane design.
Counterpanes are traditional knitted bed coverings often constructed from individual motifs or blocks that are later combined into a larger textile.
Many historical counterpane designs use geometric, floral and leaf motifs, making this four-leaf construction a natural fit for that tradition.
Margaret adapted the older concept specifically for use in afghan block exchanges and made her version available to knitters as a free pattern.
Worked From the Center Out
One of the most interesting features of the Lucky 4-Leaf Afghan Block is its center-out construction.
Instead of casting on enough stitches for one full side of the square, the knitter begins in the middle and gradually increases the circumference of the block.
As more stitches are added, the four leaf sections expand outward and the square gradually takes shape.
Why Center-Out Knitting Is Different
Center-out construction creates a very different knitting experience from working a conventional square in rows.
At the beginning, only a small number of stitches need to be managed. As the block grows, the rounds become progressively longer.
This method also makes it possible to create strong radial symmetry, which is especially useful for floral and geometric motifs.
Knitting in the Round
The Lucky 4-Leaf Afghan Block is worked in the round.
This allows the four sections of the design to develop simultaneously without creating seams between the individual leaves.
If you have mainly knitted flat scarves or dishcloths, this project can be an interesting opportunity to practice circular construction on a relatively small piece.
Starting With Double-Pointed Needles
Margaret's pattern begins the center-out construction using double-pointed needles (DPNs).
DPNs are useful at the center of a project because the initial circumference is too small for many standard circular needles.
The stitches are distributed across several needles while another needle is used to knit around the developing motif.
Moving to a Circular Needle
As the block grows, more stitches are created and the circumference becomes larger.
At that stage, many knitters find it more comfortable to transfer the stitches to a circular needle of the same size.
This can make the increasingly long rounds easier to manage and reduces the number of needle changes required while working around the square.
Aran-Weight Yarn
The published pattern calls for Aran-weight yarn.
Margaret's original recommendation is Lion Brand Vanna's Choice, a yarn frequently used for afghans and other practical home projects.
An Aran-weight yarn gives the leaf motif enough substance for the textured details to remain visible while producing a useful blanket block.
How Much Yarn Do You Need?
The 12-inch version lists approximately 150–175 yards (137–160 meters).
Actual yarn use can vary with your gauge, yarn substitution and finishing choices, so having a little extra yarn is sensible if you need the block to match a specific finished measurement.
Choosing Yarn for an Afghan Block
If you substitute another yarn, try to choose one with similar weight and suitable stitch definition.
Consider:
- Aran or compatible worsted-weight construction
- Good stitch definition
- Washability
- Durability
- Colorfastness
- How the yarn behaves after blocking
These considerations become particularly important when multiple blocks will eventually be joined into one blanket.
Solid Colors Show the Leaf Texture
A solid or gently tonal yarn can be especially effective for this pattern because it allows the shadows and raised areas of the leaf motif to remain visible.
Highly variegated yarn can still create an interesting block, but strong color changes may compete with some of the textured details.
If the four-leaf shape is the feature you most want to emphasize, consider a yarn with enough visual consistency for the stitch pattern to stand out.
Needle Size
The published recommendation is US 7 / 4.5 mm needles.
Use this as the starting point and adjust only when necessary to obtain the required gauge and finished block size.
For a modular afghan, consistent gauge is especially important because blocks that differ significantly in size can be difficult to join neatly.
Gauge for the 12-Inch Block
The listed gauge is approximately 16 stitches and 24 rows = 4 inches in stockinette.
Although the finished block contains texture and shaping rather than plain stockinette throughout, the published gauge gives you a useful reference for choosing needles and yarn.
Why Block Size Matters
If you are making only one square as a decorative piece, a small difference in finished size may not matter very much.
But if you plan to join several blocks into an afghan, matching their dimensions becomes much more important.
A consistent 12-inch size makes it easier to arrange blocks into rows and join them without stretching one square excessively to fit another.
Skills Used in the Lucky 4-Leaf Block
This project can introduce or reinforce several useful knitting skills, including:
- Knitting in the round
- Working with double-pointed needles
- Center-out construction
- Increasing
- Decreasing
- Following repeated motif sections
- Lace-style shaping
- Textured knitting
- Managing a growing stitch count
- Blocking a knitted square
Is This a Beginner Knitting Pattern?
Lucky 4-Leaf is probably better suited to a knitter who already knows the basic knit and purl stitches and is ready to work in the round.
The unusual center-out construction and use of DPNs can make the first few rounds feel more challenging than a simple flat square.
Once the block becomes larger and the motif is established, however, the construction can become easier to visualize.
The First Few Rounds May Feel Fiddly
This is common with many center-out projects.
A small number of stitches distributed across several double-pointed needles can feel awkward because there is very little fabric available to stabilize the needles.
Work slowly at the beginning and check that the stitches have not become twisted before the structure is firmly established.
Use Stitch Markers to Track the Four Sections
The strong four-part symmetry of the design can make stitch markers useful.
Separating the repeated sections can help you identify an increase or decrease error before it affects the entire round.
Always follow the original pattern's marker placement and stitch counts rather than adding markers where they might interfere with the motif.
Count Your Stitches Regularly
Center-out patterns rely on controlled increases to produce the intended geometry.
If an increase is missed, the mistake may not become visually obvious until several rounds later.
Checking stitch counts at useful points in the pattern can save much more time than discovering an error near the outer edge of the block.
Blocking the Finished Square
Blocking is particularly useful for an afghan block containing textured or lace-like shaping.
After knitting, the square may not immediately measure exactly 12 inches or the four leaf sections may look slightly uneven.
Gentle blocking can help the stitches settle and allow the square to reach a cleaner, more consistent shape.
Always use a blocking method appropriate for your yarn fiber.
Using the Block in a Knitted Afghan
One Lucky 4-Leaf block can be attractive on its own, but the design was created specifically with afghan exchanges and modular blankets in mind.
You could knit several matching blocks for a repeating four-leaf blanket or combine Lucky 4-Leaf with other 12-inch squares.
Using a consistent yarn weight and block size will make the final assembly much easier.
Try a Two-Color or Multi-Color Afghan
Although each individual block can be worked in a single color, the finished blanket does not need to be monochromatic.
For example, you could alternate light and dark blocks, create a gradient across the blanket, or use several coordinated colors while keeping the same four-leaf motif.
Repeating the same texture while changing color can produce a cohesive blanket without making every square identical.
A Useful Block for Afghan Exchanges
Margaret MacInnis originally developed her version of the block after using it in several afghan exchanges.
Standardized block sizes are useful for group projects because different knitters can make individual squares that are later assembled into one blanket.
The 12-inch format makes Lucky 4-Leaf particularly suitable for that type of modular project.
There Is Also a 9-Inch Version
Margaret MacInnis later published a separate 9-inch Lucky 4-Leaf Afghan Block.
In that version, the leaves were modified to be shorter and the border construction was changed to suit the smaller finished square.
If you need a smaller block for your blanket layout, make sure you select the 9-inch pattern rather than simply trying to reduce the 12-inch version yourself.
12-Inch vs. 9-Inch Lucky 4-Leaf
The two patterns are related but they are not identical.
- 12-inch version: the original larger afghan block
- 9-inch version: later adaptation with shorter leaves
- Both: designed by Margaret MacInnis
- Both: currently available free
Choose the version that matches the other squares in your planned blanket.
