I am not aware of anyone else who has mitered pattern. So I claim the idea unless someone can prove me wrong. Mitering a pattern allows you to create a truly unique affect. The miter involves only using 4 pieces whereas using 6 or 8 pieces gives a kaleidoscope effect.
This technique is useful if you want to feature a pattern that is not symmetric. An unbalanced pattern is not attractive as a pillow face.
While this example is square I will show you how to make a pattern that allows you to make a rectangular finished face.
Cut pattern fabric 2" longer and 2" wider than the finished size desired. Fold the fabric in half side to side and press. Fold the fabric in half again top to bottom and press.
Using the center of the press marks as a guide fold the fabric diagonally as shown in the picture.
Be sure to align the vertical and horizontal creases made in the last step and the center point.
Repeat the process in the opposite direction.
You will have two regular triangle shapes and two triangle shapes have "extensions" beyond the standard triangle shape. These allow you to have a center mitered pattern with a finished rectangular shape.
Below is the pattern that will allow you to have a mitered center in a rectangular finished face. .
For a square finished face piece you will use this first cut as a pattern for 3 more exactly like it. For a rectangular finished face piece, you will cut one more like this and then put the printed triangle pattern in position over the fabric, then place the longer triangle pattern on top of the patterned triangle pattern. Cut the first "longer" triangle pattern. By placing the "regular" patterned triangle pattern between the fabric and the white "longer" pattern you assure that the bigger triangle is properly aligned with the pattern.
In order to clearly distinguish each triangle and emphasize the mitered effect, a tiny welt cord must be sewn between the edges of the triangles as they are joined.
A fabric covered button a great finishing effect and also hides any imperfections when all four pieces come together in the center.
