I have some of the quite expensive decorators Frogtape but reluctant to use it.
I guess if I tape some cloth in place fastening it underneath as a precaution.
I like Ashs idea of cutting a hole in some thin towelling - a bit like when they do when when you have an operation with a wighted cover with a hole for where they are going to cut you open!
I wonder how much time I will spend searching for the clip when I drop it or even worse it pings into the air instead of clippiing onto pin groove.

Me overthinking and expecting the worst.
