Leni, they look wonderful like that, well done
but arent you worried about strong sunlight?
The shelf is partly shaded, and the position of the conservatory means that that particular shelf doesn't get direct sun in the hottest part of the day. Also, the conservatory glass is supposed to be made of that special 'solar control' glass. (I don't understand the technicalities, but it apparently cuts down UV / overheating in Summer and keeps heat in, in Winter!

)
But I do worry about temperature changes overnight, so I have a small oil-filled electric radiator in there which I turn on very low if I think it's going to be extra cold at night.
