I'm speaking only from my limited knowledge thus far

But it seems customers are completely ignorant on the technology and have to be told and given the ideas before the light goes off

They see engraved wood but are astonished it can also be done on a wooden door/cabinet...

Unless I have an example or tell them they never think further than what they see in front of them

I cannot get a brochure big enough to cover everything in the area im marketing for - seems I have to find a way to explain it all or miss out on someone approaching me because they just don't understand it all
