Step 1: I basecoated the marsh shapes with a custom brown latex paint, and then added a patch of darker brown near the center to represent deeper water.
Step 2: I added some Woodland Scenics pine trees to the smaller shape with tacky glue. These have been primed with grey and then drybrushed white.
Step 3: I add the flock blend around the base of the outer shape.
Step 4: I put a semi-gloss on the "water" and added a piece of Ret Rubble with an acrylic gem. Looks pretty sweet.
