My problems with foil seem to be many. First the cut pieces have to be exact. Then I can never get the foil on straight. And finally my soldering does not look that great.
Thats why I like lead. There is a little more tolerance.
As far as glass selection for my cat I have some new glass coming and hope it will meet the requirements.
Most people who can't get the foil straight are trying to put the foil on the glass.
Bend you head around this idea. Try putting the glass onto the foil. (He's crazy, right?)
Lay the foil, sticky side up, across your finger. Now place the glass in the muddle of the foil. Take a look at both sides, and see if it's pretty even.That's easy, right!!
Now take a good look at how much foil overlap you have on the "presentation side" of the glass. From now on, just concentrate on how much foil your can see on the presentation side. The back will take care of itself.
Now turn the glass, sort of rolling it along like a wheel, pressing the foil against the edge of the glass with that finger, ensuring that the amount of foil showing on the presentation side remains consistent. When you've gone all the way round cut or tear the foil off, flatten the foil onto the presentation side and the back, and burnish it.
Always be looking at the sticky side. Working from the other side might work with scotch tape - but you can see through that. We don't have Xray vision/
