LL you obviously have these items in your possession so it's not possible to contradict what you're saying, but to me, as an outsider looking in, I can't for the life of me believe that Craig would have allowed these headrests to be sent to a customer in this unfinished state without some reason.
Obviously something has gone amiss here. Have you contacted Craig for an explanation? Knowing him, he would be mortified that such a slip-up has occurred. There has to be an explanation ... Is the covering some sort of "undercover" awaiting finishing by an upholsterer ??
Or have I just blundered in here and you're taking the pi$$, and it's the underside of a kitchen chair from Ikea?
