Hi Barbara
A very politely meant suggestion if I may. When photographing glass such as this, or most things in fact, try to see how the background has a very detrimental effect on the overall picture. Particularly with your first photograph it is really quite intrusive all the detail from the background and really makes it much more difficult to both assess and enjoy the items that you post. You are by no means the only person guilty of this.
You could buy a sheet of plain mounting board for a couple of quid or simply drape a plain sheet etc over something to act as a backdrop. Give it a try and I'm sure you'll be delighted by the result.
Regards
Gareth
