In my search for older big buildings for my large city I found Clever Models LLC. I have not built a card stock model in years....and was never very good at it. But at about $10 I thought I'd try. ($2 off until 12/31 too) I pcked a smaller two story building that would go well with my 'Wrong side of the tracks' area of my city. I wanted something that would not be on 100's of other layouts so I made a few small changes.
After downloading the PDF from the Clever site I printed the pages on good bond stock. I then used 3M spray adhesive to apply the bond to poster board. After drying a while I used a new #11 blade and steel rule to cut out the major parts. I used white glue for part to part and colored all edges with Sharpie markers.
Half way though putting it together I got discouraged and was going to give up on card stock. But figured I finish this one up and set it aside. But as I got it closer to finishing I liked how it was coming together.
I did alter the building some for a number of reasons. I also added clear plastic to store front windows, made the sign support and roof top caps. I have a few things to finish up yet but will look great in the background of my Big City!
