Traditional / Public Domain — one of the oldest known quilt blocks
The simplest traditional quilt block — four equal squares arranged in a 2x2 grid. This is the very first block most quilters learn, and it forms the basis for hundreds of more complex patterns. Despite its simplicity, creative fabric choices make it endlessly versatile.
The Four Patch dates to the earliest days of American quilting in the late 1700s. It was the first block taught to young girls learning to sew, often as young as age four or five. Pioneer women valued it for using every scrap of precious fabric.
Found in quilting traditions worldwide, the Four Patch appears in American, British, and Australian quilting heritage. Its simplicity made it the universal starting point for quilting education. Many antique Four Patch quilts survive from the Civil War era, often made from dress scraps and feed sacks.

| Piece | Fabric | Cut Size | Qty | Notes |
|---|---|---|---|---|
| Square A | Dark | 6 1/2" x 6 1/2" | 2 | Includes 1/4" seam allowance |
| Square B | Light | 6 1/2" x 6 1/2" | 2 | Includes 1/4" seam allowance |
Cut two 6 1/2" squares from Fabric A (dark) and two 6 1/2" squares from Fabric B (light). Accuracy matters — use a rotary cutter and ruler for clean edges.
Tip: Starch your fabric before cutting for crisper edges and easier piecing.
Place your four squares on a flat surface in a 2x2 grid, alternating dark and light: Dark-Light on top, Light-Dark on bottom (or vice versa).
Place the two top squares right sides together. Sew along the right edge with a 1/4" seam allowance. Press the seam toward the darker fabric.
Tip: Use a scant 1/4" seam — just a thread's width less than a full quarter inch.
Repeat for the bottom pair. Sew right sides together with a 1/4" seam. Press the seam toward the darker fabric.
Place the two rows right sides together, nesting the center seams. The seams should butt up against each other since they were pressed in opposite directions. Pin at the center seam intersection and sew with a 1/4" seam.
Tip: Nesting seams is the secret to perfect intersections. You should feel the seams lock together.
Press the final seam to one side. Your block should measure 12 1/2" square (12" finished after sewing into a quilt). Trim if necessary.
