How it goes together

  1. Step 1

    Cut your pieces

    Cut each region using the dimensions in the cut table for a 12 inch finished Nine Patch block. Standard 1/4 inch seam allowance is included.

  2. Step 2

    Sew sub-units

    Sew the smallest units first (half-square triangles, flying geese, four-patches), then build outward.

  3. Step 3

    Assemble the block

    Join the sub-units into rows or columns, then join the rows. Press as you go. Square the finished block to size.

Try the Nine Patch on a real layout.

Open it on the Design Wall. Try a few colors, see the math, change your mind.
