I made pillowcases out of the left over scraps from my DD's quilt. I just sewed all the pieces together until I had a piece 27x45. Then I cut a piece of cheap clearance shelf fabric the same size and layered them wrong sides together. Then I just followed the pattern the same way I've done all my other pillow cases. My DD has been sleeping on these for 3 years now with no issues. I was concerned the seams would be uncomfortable, but I've slept on them and you don't even notice the seams.
