But I have a steel t-square for drywall & a nice razor knife and and thinking I can trim 1/16 off each side so it will fit nicely.
When I have time.
depending on how the EL panel is constructed, usually you have 2 conductive layers with the luminescent material sandwiched between them. if you cut the panel (strip) you chance ruining the strip.
if the EL panel is conducted from either sides of the material it might work if you don't break the conductive stip down the side.
look into "EL wire". this may fit your moulding better.
The two layers look like they are laminated together and the lamination is a few mm's wider on one side.
I think I can trim it without having the whole thing fall apart.
but maybe i'll grab some EL-WIRE also since it's cheap.
I just wasn't sure if it would illuminate the moulding evenly like the tape.
I don't want a bright line down the middle.
