Wanted a sign for a scale garage so here it is.
EMPI sign for the garage wall.

The letters and the logo shape are all separate so that the background shows through.
(see pics)

The Logo was stuck to the wall. Made some small holes and fed some EL wire through the wall and around it to make it look like a neon sign. This is controlled and powered from the back of the diarama.

The EL wire can be found on ebay/amazon for around £4 to £5.
