I hate to lose stuff. Right now I'm searching for a plain white pillowcase that I know I have. I have 2 of them and I rotate them on my ironing mat to keep spray starch, ect. from making the pad dirty. You can still see the lines on the mat though the pillowcase. I have 2 so I can wash one and still have 1 to use. Don't remember washing it the last time I changed them. Maybe I accidentally threw one of them away but I can't imagine that I did. Just can't find the other one. If i go buy more, I'm sure it will show up.
