Preparing for the decorators, this evening I removed a very large (133 x 95 cm) picture from the wall - and its thin glass cracked. The 15 mm frame is light and flexible, with about 14 springy metal 'bridges' securing the glass. I plainly didn't use the correct tactics in gripping it.
Before I start phoning around picture framers tomorrow, can anyone tell me if it's popular to use some sort of plastic nowadays? Glass is presumably clearer, but I don't fancy my chances of getting it back on the wall without another expensive accident!
