Four-Patch Pinwheel Block
Dimensions: 6¼" unfinished
What You Need
- Two fat quarters in contrasting colors
- Sewing machine
- Fabric pen
- Rotary cutter
- Quilting ruler
- Sewing pins
1. Cut the Fabric
Grab two fat quarters in contrasting colors and cut each into eight 3⅞" squares.
2. Mark + Pin
On the wrong side of each lighter-colored fabric, draw a diagonal line from corner to corner. Pin one lighter fabric to one darker fabric, right sides together. Repeat with the other seven pairs.
4. Cut Down the Line
If you chain pieced your units, cut the threads between the half-square triangles to separate them. Then, cut along the marked line with a rotary cutter and ruler.
5. Open Them Up
Trim off any dog ears (the tiny points that extend beyond the block unit). When you finish trimming, each square should be 3⅜".
7. Lay 'Em Out
Arrange four half-square triangles into a four-patch so the light fabrics always sit next to the dark fabrics, forming the pinwheel shape.
8. Sew Them Together
Sew together the blocks in each row, making sure to press the seams in opposite directions (both toward the darker fabric). This will create a nested seam in the next step.
9. Finish Your Block
To finish the pinwheel quilt block, sew together the top and bottom rows and press the seam in the direction of your choice.
Keep making as many pinwheel blocks as you want, and use 'em in your next quilt!
