oh, crikey, I don't half struggle with cut stuff!
(to my non-flowery eyes, everything flowery just looks the same...... fancy-flowery :spls: )
I was having a peek at claretjugcollector's champagne glasses, because I thought they looked a bit like this, but having checked, they're not.
However, there's been talk of Tudor, for which I have always harboured a small affection, because I have a set of (post-war) wine glasses which belonged to my Grandpa. There is cross-hatching on the centres of the flowers in your piece and in my glasses - but the flowers on my glasses are thistles - there's a strong liklihood that this is just the way thistles are depicted, rather than it being any sort of "feature" typical of any maker.
Your glass is pretty tall - is it a wine glass? or something completely different?
