I bought a layer cake of Joy by Kate Spain from Pink Castle Fabrics earlier this year (I think Brenda has sold them all now) and the prints were just what I wanted for this piece. The layer cake pieces weren't quite big enough, so I made a quick trip to my LQS for a few fat quarters and I was in business.
Here's what you'll need:
Fabric A (center): 8" x 8" square
Fabric B: 2 3½" squares and 4 3" x 8" rectangles
Fabric C: 4 3" x 8" and 4 2½" x 9" rectangles
Binding: approx 60" x 2½"
Batting and Backing: 22" square
Sew the 3" x 8" rectangles from Fabrics B & C together on the long sides. If your B print is directional as mine is, sew the "bottom" of B to the "top" of C. Press toward C. Make 4.
Cut the 3½" squares on the diagonal to make 4 triangles.Mark the center of the longest side of each triangle with a pin. Match, right sides together, with the center of a 2½" x 9" rectangle. Stitch and press toward the triangle.
Line up the corner of your ruler with the corner of the triangle. Trim excess Fabric C rectangle to make a B/C triangle.
Lay out your centerpiece in three rows as in the diagram. Sew the three pieces in each row together. See below for the top and bottom row.
The triangle units are over-sized, so in sewing them to the rectangle units, match the B/C seam and not the edges. I put a pin 1/4" from the raw edge at the B/C seam on each piece and pinned it in place.
Your top (and bottom) row will look like this:
Notice that the triangles are bigger than the center rectangle on both the top and bottom edges.
Trim the triangles on the long edge even with the center rectangle unit.
Sew the three rows together. You can trim the outer triangles now or wait until you have quilted the centerpiece.
Now you are ready for binding! It might look tricky to bind an octagon, but it really isn't. Miter the binding corners the same way you would on any quilt and it will work out fine.
If you are interested seeing more projects with Joy, hop on over to the Fat Quarterly blog (or Moda Bake Shop) where they are showing a quilt and pillow from their Christmas issue.
