When I restore a broken piece of painted glass – restore it: so I mean when I “re-paint” it, not glue it, which I call “conservation” – there’s a big mistake I almost always make.

I say “almost”. Really though I should say “a mistake I always make – and then, just in time, I catch myself, start again, and do things properly”, thank goodness.

I want to tell you more. I want to – confess. But not just because my full confession may help you. (I can’t pretend I’m quite so selfless.) No, if I’m honest with myself, I’m fed up with this mistake I always make. It will be wonderful if, the next time I restore a broken piece of painted glass, I avoid this foolish error and get things right immediately.

So maybe – maybe! – by setting this down before your eyes, I’ll help myself.
