Preferably, use a perforating wheel to cut,
but in lack of such, you can cut along lines with a scalpel,
taking care to not cut all the way to the edge.
We are hooked on Michaels hooks. We have a bit of history with Michael. Back in 2010 we had a temporary store-in-shop at SCP in London; it was Michael who built the display. It was such a good display that people still come up and talk to us about it - specifically how great the display was. He's an incredibly sympatico person with so many good designs popping out of him. This one is simple yet ingenious and also exactly how I want my coat hooks to look like, if only I had the time to bend! Incredibly, it fits on any wall wider than 3.75 inches - please measure before getting and putting. Batteries are not, but screws are included.
