So here is what I've come up with for alternate apron art. These are designed to be used with flush LED's (HH's idea of bending the sockets and installing flex bulbs is best). The first pic is not great as I just used a flashlight shining in from under the side to show how the light shines through, so light was not direct which caused shadows. The other pic is with a red flex which I think looks best, although the camera doesn’t do the deep red justice.
Anyway, these would be printed on photo printer with ultra gloss paper, coated with gloss laminate, and have an adhesive backing. I would sell them for $20 a set including postage to US (outside of US shipping would need to be calculated on a per-order basis). If you would like me to include 4 x non-ghosting 1 SMD super bright flex bulbs, then the price including US shipping is $32 (in addition to including bulbs, I will have to ship in a box vs. standard envelope which is why price is higher.
PM me with any questions or if you are interested in purchasing.
