Kevin/Ryan - I'm definitely planning on hiding the seams. I'm wondering which would be the most efficient way. I was thinking I could use some posterboard but that would need to be carefully cut and arranged. I could also use Masking Tape which would be much faster. Anyone have any experience with masking tape peeling off after spray paint is applied? I seem to recall that one of our early test buildings used this approach.
Looking great so far Brent! Like Famine was saying cover up those seams a wee bit aznd they will be great. And just out of curiosity how big is that table there, 3' x 5' maybe?
As for the trees... Would you mind trying to make maybe two more? I was thinking that we can try have about two for each 2' x 2' section of terrain. If you don't want to that's fine too. Let me know either way.
I checked the table - its 3.5' x 5.0' - good eyes! I don't know if you are thinking the same thing I am but I'm actually worried that the diorama space will be too small

I know that seems like its counter-intuitive to everything we've said recently. However, with 6-10 buildings, plus the large items from Chewie (including the junkyard), plus the market. Are we going to need more real-estate?
I think my buildings will be fine for the diorama, but like I've said all along - these are "rank and file" type buildings and not intended to be the "stars" if you know what I mean. We really need to have enough room to show off some of the extra special buildings. I know in your standard building description, you said mostly single story. However, I think we'll need some larger (i.e. taller) buildings to really comform with Glassman's original concepts.
As far as the trees go. Let me finish the 6 I've got started. I think I'll be able to do two more but I want to get these first ones completely finished up.
