C. C. Crow Stone Church - First Annual Raymo Build Challenge 2016

[S&S RR]

Step 4: The Burnt Sienna Extra Dark Stones.

[S&S RR]

This is the same technique I would use if I were using acrylic paints. Pick random stones to have this predominant color and then blend it all together like mother nature does.

Step 5: Add Burnt Sienna Shade.

Step 6: Add red iron oxide extra dark.

[S&S RR]

I'm using three shade of grey and three shades of burnt sienna. My artist friend tells me mother nature always uses three shades of every color.

[S&S RR]

Here are my three shades of gray - the predominant color for this casting.

[S&S RR]

Step 7: Add the predominant blend color - a neutral gray in this case. At this point I move from using sponges to using a brush to blend all the colors together.

A few more shots as I completed the process on all three castings.

Now in Step 8: We add a little moss to the stones with a green shade.

[S&S RR]

In Step 9: We use a dry brush like technique with a lighter shade of grey to add highlights. The difference between a darker gray stone wall and a lighter one is the color we use to blend the colors together.

Step 10: For these walls - was a spray of fixative - I used the one from this can.

[S&S RR]

Here is what the wall looked like after the fixative dried.  I will not be using this on the church walls.  I got rid of gloss with a dry brushing of the lighter gray but no one will be touching this structure once it's on the layout so I'm going to go with the nice flat finish and texture of the pastels without the fixative.

[S&S RR]

Here is the walls after I dry brushed them.

[S&S RR]

Notice how the highlights show through from the two different primers on the casting on the left. It's time to stop playing and get on with the build. What do you think?

Next step  - making the shingle castings look like cedar shingles.
