I've tried Google, but end up with too many bad hits...

I'm trying to figure out what to ask for when looking for 1/8" wide and 1/4"
wide black "pinstriping" tape. I'm using it to make some faux stained glass.
Electrical tape should work - IF they made it in those widths.

I've been able to located the actual tape made by stained glass kit
companies, but at $5.00 for 2 feet, that's a bit outrageous.

My only real concern is how easy will it be to remove later on.

Any suggestions?
