About toast, Giorginetto, still not sure about it. I acually do not like that it is brown, while the walls are grey. I'm still thinking about alternatives. Also I think I want a part that is flush with the walls. But it might be too labour intensive.
I buy from our local ad-site. Loose toast is very rare on it. Might buy them from ebay.
Mina, this is only the first mock up. I will post other versions as my work progresses. I'm pretty sure I'm going with this basic lay out.
Karim, there is going to be even more magic in them.
Thanks everyone!
