Small Recovered Cushion with Zip

I made this cushion cover in a couple of hours and it has a Zip! 'Tis my husband's neck pillow for his chair and desperately needed recovering. I bought the fabric from the charity shop for abut 40p and had the zip from years ago in my stash. The fabric was a type of wrap and although it looks snagged, that's the way it's supposed to be.
