I've been planning forever to make some for my sewing things and just random use for my husband and I, there just never seems to be the time. I think one in the van for extra sweaters, books, and toys would be a great help. I salute you on your endeavor to make slip covers, I would never finish that.
Which brings me to the point of my response, finally. Have you considered using the pockets somehow to make a place for remote controls, books, magazines, eyeglasses, dog toys, that sort of thing? I don't know what sort of shpes your covering, it may not be appropriate.
I had to experiment with how to make them hang in closets, off the backs of doors, etc. I was hanging the pants, not the kids, I swear! Although...
I don't know what they may be called in Britain, after all you have bonnets on your cars
