Cathedral Window demonstration

This Cathedral Window demonstration yields a 9" x 9", four-pane window. Traditionally, Cathedral Window quilts are made using a white or light-colored fabric as the base or background. In this demonstration, two patterned fabrics are prepared to create a checker-board background. It is probably a good idea for first-timers to begin with a white background. Some of the issues that need to be considered when using patterned fabric are not relevant when using white fabric. 

Cut four pieces of fabric at 9"x9" - for a standard window, use four pieces of white fabric.
In this demo, I will use two pieces of pink and two of the red flower/orange background.

Fold the square of fabric into fourths and press

Open up square. If your fabric has a pattern, place it pattern-side down

Fold one corner into the center and press

Repeat the above step for the remaining corners until your square looks like this

Fold one corner toward center and press as before

Follow above step with remaining corners

Repeat above steps for remaining three squares until you have
four squares folded and pressed like so. If you are using white
fabric, the layout doesn't matter.  

Take two of the squares and turn up the corners in order to sew them together

You can hand-sew or machine-sew all of the following seams.
If hand-sewing, use a running stitch or back-stitch.

Once the seam is complete, fold corners back down and press.

Repeat above steps in order to sew bottom two squares together

Now you have two rows of sewn squares. Make sure to press well.

Line up top and bottom rows and lift up matching corners. 

Pin in preparation to sew the top and bottoms together.

Sew both pairs of corners along the pressed line with a running stitch or
backstitch or with your sewing machine.

Once top and bottom rows are sewn together, fold all corners back down and
press your window frame flat.

This is what your window frame will look like from the back if you use
two contrasting fabrics to create a checkerboard.

Pin all corners down. Cut four pieces of fabric at 2.75 inches square to be the panes in your window.
These can be four pieces of the same fabric or four different fabrics. The design is up to you. Pin the
squares into place. The next tutorial will explain how to sew down the window panes.
