On the underside

This was a surprise purchase, but I've been making curtains recently and having to press seams on a towel on a kitchen work top. As I've still a couple of pairs to make this seemed like a good solution. It's also significantly lighter than my old one so I'll need to store carefully to ensure it withstands the next 37 years ! Sounds weird writing that, as clearly if it does, it will outlast me.
