Hi Bob
Thanks for a quick reply, It is appreciated.
I did think after I'd posted the message it was a bit of a silly question as most glass is square or rectangle, some round so in a way it was pretty obvious,
I was thinking of other objects to be painted as well also with the self adhesive film and acetates there would be more options for painting,
I've just followed your link and had a look I saw the designs you suggested (shame there are no pictures )
I noticed there are small oval ones and large oval ones do you know roughly what size the small oval ones are?
Thanks for your help.
