How to Make a Carpenter Star Quilt

By Ruth O'Neil

The carpenter's star quilt is basically made from all triangle pieces. The triangles are arranged so that it looks like the star is made from diamonds instead. This quilt looks like a pieced star within a star. Piece one star that is the center of the quilt and then piece together an outline star for the outer edge of the quilt. You need three basic colors for this quilt. Choose two contrasting fabrics such as blue and green as well as a background fabric, such as cream or white.

Make a quilt that measures approximately 56 inches by 68 inches. Cut out the fabric using the roller cutter, straightedge ruler and mat. Cut 32, 6 1/2-inch squares from the cream background fabric, 20, 6 1/2-inch squares from the blue and 24, 6 1/2-inch squares from the green.

Cut 16 of the cream squares in half along the diagonal to make half triangles. Cut all of the blue and green squares along the diagonal to make half triangles.

Use the graph paper to make a quarter block grid. Divide the grid into 16 squares (4 by 4). Number the squares, starting from the upper left corner across the first row, continuing to the bottom of the grid.

Divide grid squares number 3, 6, 7, 9, 10, 12, 15 and 16 in half along the diagonal from the upper left to the lower right. Divide grid squares 4, 8, 13 and 14 in half along the diagonal from the lower left to the upper right corner.

Fill in the following triangles with blue colored pencil: lower 3, lower 6, upper 7, upper 10, lower 12, lower 13, upper 14 and upper 16. Fill in the following triangles with green: lower 4, upper 6, lower 7, upper 8, upper 9, lower 10, upper 15 and lower 16.

Arrange your fabric pieces in the order of the grid block. Sew the pieces together.

Make three more quarter squares following the same grid.

Sew the four pieces together to make the carpenter star.

Cut four 4-inch wide strips of the green fabric to the width and length of your quilt top. Sew the strips to the sides of the carpenter star to make a border.

Layer your backing and batting with the quilt top. Hold the layers together with straight pins. Use a large needle threaded with embroidery floss to knot the quilt.

Fold the backing edges of the quilt up and over the top edges all the way around. Tuck the raw edges under and pin and stitch into place. This acts as the binding of your carpenter's star.


Wash, dry and iron all of your fabrics before cutting for best results. Otherwise one of the fabrics might shrink, distorting the finished quilt top after you wash it.

One of the things that will make your carpenter's star quilt come out its best is to iron each seam after you sew it. This keeps the seams flat and helps them fit together better.
