Ok. So I don't want it rounded... just done enough so that it isn't sharp. Will do.
When I do this... how thick does the silicone need to be between the glass pieces and the bead on the inside?
I don't have any clamps. Can I use something like duct tape to hold it together? Does it need to be help really tightly together or what? How do I know I have it right?
Sorry about so many questions... I am so afraid of messing up!
Thanks again!
