My name is Sue, How do you do?

We are very used to imaginative descriptions,

but I think we might use the word lobes rather than petals. Lobes gives an idea of substantialness, while petals sound delicate.
Loads of us find we use food to describe glass for the descriptions of colour and texture... jelly, custard, etc.
An indication of what sort of glass - pressed, moulded, blown, old, new, helps a lot.
Don't worry about it - we were all new to it once. I've learned almost all I know from the good folk here, either directly on the gmb, or because we've become good friends off board and get together in reality (not often enough) to go hunting and blethering glass.
