For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.
Now that "Old World Charm" is essentially done it is time to be planning the next layout. I do not have a definite idea yet but am leaning towards another whimsical theme. I do not want to be to whimsically extreme this time. A balance between whimsical and somewhat scale is what I think I will strive for.
To that end I have built a station and water tower. Both are constructed with a foam board basic structure with the remainder being cardstock. Painted with acrylics. I really enjoy building with cardstock. Not only is it inexpensive but it is easy to work with and very flexible. It can be used to represent wood, brick, block or steel. It glues easily and accepts any paint. Paper and cardstock become very strong once a little thin CA is applied. That is how the metal on the light pole is made as well as the spout on the water tower.

Look out for some pizza boxes, sometimes they are made of a very good quality.
If you feel you can afford it, I recommend art paper from an artist shop. They have several types to choose from. Not cheap, but very good. I use a rather thick paper type which has a perfect surface structure for tiles or bricks when painted. Also very easy to bend or change forms of in other ways. Mine is called "Watercolour Studio" and is 300 g/m2 (or 140 lbs).
Very good models, Bob. The whimsical nature is great. I agree with your comments about card and it's suitability for modelling a large variety of materials. Personally I find pva adhesive can achieve similar results to the CA without the nasty chemicals.
