I'll bear it in mind

It seems a shame to have a nice sturdy metal notice-frame sitting empty.

I might pop back and measure it then pop back again with something to put in it.

I've been meaning to get round to doing something of that sort of thing for a while. I did put a few sets of ping-pong ball eyes on police boxes but they've all since fallen off. I still have a few balls left but will get some form of glue which weathers better than Sticky Fixers.

More later...
