The Pinwheel Fantasy Quilt is a colorful scrap-friendly design by Becky Petersen of Quilted Twins. Built from small blue squares, pieced sashing, and double pinwheel cornerstones, the finished quilt creates a beautiful sense of movement while making excellent use of leftover fabric.
The original quilt finishes at approximately 90" × 102", making it a generous bed-size project. Although the quilt looks intricate, most of the construction relies on familiar patchwork techniques that can be worked on one unit at a time.

About the Pinwheel Fantasy Quilt
Pinwheel Fantasy began as part of Becky Petersen’s series of quilts made from upcycled and leftover blue fabrics.
Instead of using one matching fabric collection, she worked with many shades of blue and arranged the small squares from light to dark. Rotating the completed blocks allowed the lighter areas to meet toward the center and created larger secondary designs across the quilt.
The result is a quilt that feels much more complex than an ordinary grid of scrap squares.
Why This Design Works So Well for Scraps
The main blocks use 2.5-inch squares, making the project a natural choice for a well-stocked scrap bin.
Instead of worrying about perfectly matching prints, concentrate on value:
- Light blues
- Medium blues
- Dark blues
- Cream or off-white background fabrics
Sorting scraps by value before sewing makes it much easier to reproduce the light-to-dark movement seen in the original quilt.
Fabric Requirements for the Original Quilt
For the approximately 90" × 102" version, the official pattern calls for a substantial collection of blue and cream fabrics.
- Approximately 5 3/8 yards of assorted blues for blocks, sashing and border units
- Approximately 2 5/8 yards of cream
- Approximately 2 1/2 yards of medium or dark blue
- About 1 yard for one of the wider borders
- About 1 yard of light blue for half-square-triangle units
- Approximately 3/4 yard for binding
Because the original design was intended to use scraps and upcycled fabrics, these amounts do not need to come from single continuous cuts. That makes Pinwheel Fantasy particularly useful for working through a large collection of blue remnants.
The Main 8.5-Inch Scrap Blocks
The quilt contains 36 main blocks. Each block measures approximately 8.5" × 8.5" before being sewn into the quilt.
Each block is assembled from 2.5-inch squares arranged so that the color value gradually changes across the block.
This value transition is one of the secrets behind the finished design. When several blocks are rotated and joined together, larger areas of light and dark begin to appear across the quilt top.
Sort Before You Sew
Before assembling the blocks, divide your blue scraps into rough groups:
- Very light
- Light-medium
- Medium
- Medium-dark
- Dark
The groups do not have to be perfect. The goal is simply to make enough difference between neighboring sections for the gradient to be visible.
Do Not Judge the Design from One Block
A single Pinwheel Fantasy block may look like an ordinary patchwork square. The interesting effect appears when several blocks are rotated and placed together.
Before sewing your quilt top permanently, lay the blocks out on a design wall, floor, or large table.
Try rotating individual blocks until the lighter sections begin to interact with neighboring blocks.
Take a Photograph
Once you like the arrangement, take a quick photograph with your phone. It gives you an easy reference if blocks become mixed up while the rows are being sewn.
Pieced Sashing Adds Another Layer of Patchwork
Pinwheel Fantasy does not use plain strips of fabric between the main blocks. Instead, the official design includes pieced sashing units made from small blue rectangles and cream fabric.
These units connect the scrappy blocks without visually stopping the movement of the quilt.
The original pattern uses 84 sashing units, each measuring approximately 4.5" × 8.5".
The Double Pinwheel Cornerstone Blocks
One of the details that gives Pinwheel Fantasy its name is the collection of small pinwheel units positioned between the larger blocks and sashing.
The original quilt uses 49 double pinwheel cornerstone blocks, each measuring approximately 4.5" square.
These blocks introduce diagonal movement into an otherwise strongly gridded layout.
Handle Triangle Edges Gently
The small pinwheel pieces contain bias edges, which can stretch easily. Use a light touch while sewing and pressing.
If your fabric feels unstable, a small amount of quilting starch can help keep the units under control.
Tips for Accurate Small Pinwheel Blocks
Press Carefully
Press rather than aggressively sliding the iron across your pieces. This is especially important when working with small triangles.
Trim Dog Ears
Removing the small triangular tips that extend beyond finished units reduces bulk where several seams meet.
Match the Center First
When joining the two halves of a pinwheel, align and pin the center intersection before worrying about the outside edges.
Check Unit Size as You Go
Small errors can multiply across a large quilt. Check a few units before batch-piecing dozens of them.
How the Quilt Top Comes Together
The finished design alternates three important elements:
- The 8.5-inch scrap blocks
- The pieced sashing units
- The small double pinwheel cornerstone blocks
These elements are first assembled into rows and then the rows are joined to form the center of the quilt.
The official pattern includes diagrams showing the exact orientation of every unit. Keep the PDF open while assembling the rows because rotation is especially important in this design.
Border Design
Pinwheel Fantasy uses several borders rather than one simple outer strip. The changing widths and colors frame the busy patchwork center while extending the blue-and-cream theme.
One particularly interesting element is an additional border made with half-square triangles.
If you already save bonus triangles from other quilting projects, this can be a useful place to incorporate them.
Tips for Making a Large Scrap Quilt
1. Work in Batches
Instead of trying to complete one block from beginning to end, cut and sew similar units together. Chain piecing can save significant time when making dozens of repeated pieces.
2. Keep Value Groups Separate
Use labeled containers or small piles for light, medium and dark scraps. This prevents the gradient from becoming accidentally unbalanced.
3. Measure Your First Block
Before making all 36 blocks, complete one test block and make sure it finishes at the expected size.
4. Use a Design Wall
The final block rotation affects the appearance of the entire quilt. Seeing several blocks together makes layout decisions much easier.
5. Photograph Every Final Layout
A photo is especially valuable when assembling a large quilt in several rows. You can quickly confirm block orientation before joining each section.
Can You Make Pinwheel Fantasy in Other Colors?
Absolutely. Blue creates a calm and cohesive effect, but the same concept can work with almost any color family.
- Red, burgundy and pink
- Green from sage to forest
- Purple from lavender to plum
- Brown, tan and cream
- A complete rainbow arranged by value
- Black, gray and white for a modern version
The most important feature is not the exact hue—it is maintaining enough contrast between the light and dark areas.
Is Pinwheel Fantasy Beginner Friendly?
The individual patchwork techniques are approachable, but this is a large quilt with many repeated units and some small triangle piecing.
A confident beginner who already understands a consistent quarter-inch seam, basic patchwork, and half-square triangles can certainly tackle it, but the project is better approached gradually rather than as a first-ever quilt.

Common Mistakes to Avoid
- Ignoring fabric value: separate light, medium and dark scraps before piecing.
- Sewing every block in the same orientation: experiment with rotations before assembling the quilt top.
- Stretching the pinwheel triangles: handle bias edges gently.
- Skipping unit measurements: check your first few blocks before chain-piecing the rest.
- Removing blocks from the layout without a reference: photograph the final arrangement first.
