15mm Stone Walls

If you have followed past posts, I was spending a lot of time and effort to scratch build stone walls for 1/300 scale. Most of these attempts were less than satisfactory in my view. Having spend a lot of time recently painting up 15mm medieval and fantasy figures, and having made some 15mm structures in the past, I decided I wanted to make a few stone wall pieces at this figure size. 

If you watch any of the tutorials out there on making your own terrain, the number one building material is pink insulation foam. It the modeler's dream material. It can be cut, carved, and embossed. Buy a foam cutter and there is no limit on what you can do.  Unfortunately, pink foam is getting to be rather expensive. If I go to my local home improvement store (called DIY stores in other countries), I would have to buy it in large sheets that cost around $40 and that I don't think will fit in my minivan. In the USA, many of these stores will no longer cut a lot of building material because of potential toxic dusts and work safety concerns. Frankly, I don't really need 4'x8' sheets of the stuff.

What I used for my walls are the foam trays that are used as a sturdy base for packaging food items such as cuts of meat. One of the complaint that I heard about using this material is that it cannot be embossed.  I found that if you use a craft knife or single-edge razor blade, you can shave off a thin layer of the outer surface leaving a squishier surface that can be embossed. There is also different grades of this packing material and some seem to be closer in consistency to the pink insulation foam. The foam I used for my first wall section was more resistant to embossing even when I shaved it. Another foam tray (shown below) was more pliable.  Of course, its the luck of the draw what you end up getting. 

I cut strips of the foam of a more-or-less uniform width. I then embossed the stones with a ballpoint pen. Once embossed on both sides, I then glued them onto thin craft sticks that I bought for another project I'm working on. I rounded off the tops a best as I could using my craft knife and some light sanding. 

In addition to the long, straight sections, I also did some corner sections. I tried to make the ends of the wall sections as flush as I could, but they are not seamless continuations. 

For one of the long sections, I decided to have a gate. I built it out of pieces of styrene plastic. 

Once the glue dried, I sealed the walls with a mixture of Mod Podge, black, and burnt umber craft paint. When that was dried, I went over the stones with repeated dry brushes of gray. The base I painted brown and then flocked.

I was surprised that once I figured out the technique, I could quickly put out a number of walls. I think the whole project took about two nights to complete three long sections and two corner sections, and that was because I wanted to sealant to dry thoroughly. The gate was probably the most time consuming part of the project. Is it a high quality job? No. But it looks fine for the table top.
