Alex,
Thanks for your answers to my three questions. Your help is greatly appreciated.
I am going to build a mall scene similar to yours shown on this page. More questions:
How high are your storefront cutouts? They look to be 3-4 inches tall. The size looks perfect and I would like to duplicate the scale.
What paper did you use to get the lights to show through? I normally use top quality photo paper, but it seems too thick to get light to shine through it.
I will do a row of LED's outside the cutouts, but it looks like you built a backstop of a sort to mount LED's a few inches behind the cutouts. Is that correct?
Finally, what tool(s) did you use to cut the foam arches so smoothly?
