The Pin Twist Star Quilt Block Pattern is a striking patchwork design filled with movement, sharp points, and beautiful opportunities for using colorful fabric scraps. Its rotating construction creates the impression of a star spinning around the center of the block.
Although the finished design looks intricate, it is assembled from four matching quarter units. Each unit is rotated before the final assembly, creating the distinctive Pin Twist effect.
The free PDF pattern available at the end of this article includes detailed cutting instructions, colorful assembly diagrams, a full-size half-rectangle triangle template, and a coloring page to help you plan your fabrics.
Pin Twist Star Quilt Block Pattern
This pattern is suitable for a confident beginner or intermediate quilter. The basic squares and half-square triangles are beginner-friendly. The half-rectangle triangles require additional attention, but the full-size foundation paper-piecing template included in the PDF makes it easier to achieve accurate points. If you have never made an HRT before, consider testing the template with scrap fabric before cutting your favorite materials.
This block combines traditional patchwork units with elongated triangles that give the star its sharp and dramatic appearance.
The complete design is made from four 6-inch quarter units. Once the units are completed, they are rotated in different directions and sewn together to create one 12-inch finished block.
The construction uses:
The half-rectangle triangles, commonly called HRTs, are responsible for the long points that distinguish this design from a traditional star block.
The completed Pin Twist Star Quilt Block measures:
Each quarter unit measures:
The measurements in the pattern include a standard 1/4-inch seam allowance unless otherwise indicated.
To make one 12-inch finished block, you will need:
A square quilting ruler is especially helpful when trimming the half-square triangles.
The Pin Twist Star Quilt Block is perfect for using leftover fabric from previous quilting projects.
Each quarter unit can contain five different color roles. You can repeat the same fabrics throughout the block for a coordinated appearance or use a completely scrappy selection.
For a design similar to the illustrated version, try combining:
Choose a light neutral background if your colorful fabrics are medium or dark. If you prefer a dark background, use bright or light-colored scraps so the star remains clearly visible.
Solid fabrics emphasize the geometric construction, while small-scale prints create a charming scrappy appearance. Avoid large prints because some of the fabric pieces are relatively narrow.
The secret behind this block is its quarter-unit construction.
Every 6-inch finished quarter unit contains:
The pieces are arranged into three vertical columns.
The first column contains a colored square above a long HRT. The center column contains one HST, a background square, and another HST. The second HST is rotated 180 degrees. The third column contains an HRT above another colored square.
Once these three columns are sewn together, the quarter unit should measure 6 1/2 inches square.
Make four quarter units using the same construction.
The half-square triangles can be made using the two-at-a-time method.
Place one colorful 3-inch square and one 3-inch background square right sides together. Draw a diagonal line from one corner to the opposite corner on the wrong side of the background square.
Sew a 1/4-inch seam on both sides of the marked line. Cut directly on the drawn line and open the two resulting units.
Press the seam toward the colorful fabric and trim each HST to exactly 2 1/2 inches square.
You will need two matching HSTs for each quarter unit, for a total of eight HSTs.
The long HRTs finish at 2 inches wide by 4 inches tall. Before being sewn into the block, each unit measures 2 1/2 by 4 1/2 inches.
Unlike an HST, an accurate HRT cannot be created by simply cutting a rectangle diagonally. The seam allowances must be offset correctly so that the points remain aligned after sewing.
For this reason, the downloadable PDF includes a full-size mirrored foundation paper-piecing template.
Print the template at 100% or Actual Size. Do not select “Fit to Page” or “Scale to Fit.” Measure the 1-inch test square before using the template.
Make eight HRT units for one complete block.
After making the four quarter units, position them as follows:
The four colored corner squares of the quarter units should meet in the middle, forming the colorful center of the block.
Sew the two upper units together and then sew the two lower units together. Match the central intersections carefully.
Finally, join the two rows and press the last seams open to reduce bulk around the center.
The completed block should measure 12 1/2 inches square before it is added to a quilt.
Use these tips to keep the long points and center seams aligned:
A small difference in one HST or HRT can affect several intersections, so checking each unit during construction is much easier than correcting the finished block.
One Pin Twist Star Quilt Block can become the centerpiece of several beautiful sewing projects.
Use a single block to make:
For a larger quilt, make several blocks and join them directly together. The repeated stars will create secondary geometric designs between the blocks.
You can also add solid sashing between the blocks to give each colorful star more visual space.
One of the best features of this design is its flexibility. No two quarter units need to use the same fabrics.
I hope you enjoy choosing your fabrics and watching this colorful spinning star come together. Save the pattern for your next scrap-friendly quilting project and share your finished block with other quilters!

The background creates continuity while the colorful scraps give each point its own personality. This makes the pattern an excellent choice for using small pieces saved from previous projects.
For a more controlled look, choose five coordinating fabrics and repeat them in every quarter unit. For a lively vintage-inspired quilt, use a different combination in each section.
