Nice but… Can You Make a Pillow Case to Go With?

I really like this Small Buckwheat Pillow, but the size I bought (great for travel) has made it impossible for me to find a pillowcase that fits it. If you’re going to make a weirdo-size pillow, at least sell a case to go with. No one sells this size case. I guess i’ll have to make my own. Annoying.
