Your fabric could be measured and cut but since there are some angles, it is best to make the pattern on paper first.
- Draw one rectangle that is 13 1/2" by 17". Use the 13 1/2" edge as a straight grain line. This will be the front part of the pillow that is under the envelope flap.
- Draw a rectangle 10 1/2" by 17". Mark 3" from the bottom on both 10 1/2" sides. Find the center of the top 17" edge. Draw lines from the 3" mark to the center mark. Use the 3" edge as a straight grain line. This will be the lining piece for the flap of the pillow.
- Draw a rectangle 17" by 21 inches. Mark 7 1/2" down from the top on each 21" edge. Find the center of the 17" top edge. Draw a line from each side marking to the top center marking. Use the 13 1/2" edge as a straight grain line. This will be the back and flap piece.
- Use the final marked lines as the pattern pieces. (The black lines in the diagram.)
- Cut out one of each pattern piece. The facing can be cut out of a complimentary fabric if you are short on the pillow fabric.
All directions refer to a 1/2" seam allowance unless otherwise noted.
