Living the Dream

27" for the body is fine if the pattern is non-directional, like the deep blue snowman and reindeer pillowcase.

But if there is a directional picture and you want the picture to run the length of the pillowcase, like the light blue snowman/reindeer pillowcase or the birthday pillowcase, you'll need to sew the cuff to the selvage edge. You'll need 45" of fabric (instead of 27").

There will be fabric left over along the other selvage.
