I have questions now. What did you use for the interior wood flooring and interior brick paper? What did you use for the exterior brick mortar? And how did you do the Penn Produce signs on the exterior brickwork?
thanks, I'm always in learning mode...
The flooring is an image of a real wood floor that I photoshopped and printed on cardstock.
The brick walls are done in a similar manner. But I started by taking a closeup photo of one of the plastic model brick walls, which photoshopped into a blank wall without windows. By using a photo of the model wall I assured that the color and size of the brick would match the model. It was printed on cardstock and glued in the interior.
For the mortar I use DAP Vinyl Spackling. I have used this for many years and it gives good results. It is very forgiving. Even after it dries it is water soluble so it can be washed off with mild soap and water. I smear it across the wall lightly enough to fill the cracks, let it dry for a few minutes, and then use a slightly damp paper towel or rag to wipe over the surface to remove the excess spackling. I go over the surface very thoroughly to remove excess spackling from tight corner, etc. I eventually "seal" the mortar by spraying the model with a flat finish.
The Penn Produce sign I created myself using an image I found on the internet and adding text. I usually create signage like this in PowerPoint. It was printed on decal paper that can be printed in a regular inkjet printer. It is an easy way to create you own custom decals. The decal paper is readily available from a number of sellers on Ebay. The standard "colors" are white or clear.
