How to make grass for a diorama? There are many questions that people ask themselves when they are trying to create the perfect scenery. One of these is how to make grass for a diorama, which can be difficult because you need something that will stay in place and not fall or crumble. Luckily, some tricks go into making this easy!

What you will need:

You will need a few basic materials to create your grass. You can find these at many big box stores or craft stores such as Michael’s, Hobby Lobby, and so on.

  • Flock (the green stuff you see in model railroads)
  • PVA Glue
  • Acrylic paint: dark brown and light green
  • An airbrush or paintbrush
  • Colors in earth tones (reds/yellows/browns)
  • A hot glue gun and sticks
  • Static grass applicators (or analog)

What types of grass can I use?

You can use a variety of different grasses, but some work better than others.

  • Flock: This is the most common way to create your own grass for diorama making. It comes in many colors, and you do not have to worry about buying acrylic paint because it is already green! The downside with this method is that it does shed off quickly when touched or blown away by the wind.
  • Moss: You need moss if you want more realistic looking grass that has depth and will stick around, unlike a flock
  • Fabric/felt scraps or yarns are excellent materials for creating rough terrain such as hillsides where the soil would be loose and cascading downhill. If desired, these can also be painted brown, so they blend in with the ground.
  • Model railroad turf: This is an excellent material for creating grass because it comes pre-colored, and you can also glue this down to make it stick more easily

How to Prepare The Soil For My Grass?

Before gluing down your material, you need to create some soil for it first. You can use any color that will match the diorama or scene you are making! This is often a light brown but doesn’t have to be.

  1. Paint your base (the area where you will place your diorama) with acrylic paint in whatever shade of brown/earth tone you desire
  2. Let this dry completely before proceeding.
  3. Mix up PVA glue and water together until it reaches desired consistency (runny-like syrup works best!)
  4. Using an old brush, apply the mixture on top of a painted surface, making sure not to cover the entire thing evenly if using one color; do multiple thin layers rather than one thick one.
  5. Sprinkle some soil on top of the surface while it is still wet to give a little texture. When dry, brush off excess with an old paintbrush or your hand

In this post, I’ll go over PVA glue in detail.

Other Things You Can Use For Your Diorama (Such as Rock, Moss, Bark)

Rock, moss, and bark are not the only things you can use for your diorama. You may have other materials lying around that would work just as well – if not better!

For example, leaves could be used to create a forest scene. Paper towels or toilet paper rolls can be made into buildings. Scraps of cloth or old clothing could become an animal’s fur coat. Even junk mail or newspapers might find their way into your project!

The possibilities are endless if you’re willing to think creatively about what you’ve got on hand. And it doesn’t matter how messy they look; chances are no one will notice once the piece is put together in its final location anyway!

Steps To Make Grass For a Diorama

Step 1: Gather Materials

  • A box cutter or X-Acto knife
  • Styrofoam (available at craft stores)
  • Hot glue gun and hot glue sticks
  • Acrylic paint in green, yellow, blue, brown, etc. for coloring the grass
  • Paintbrush(es) to apply paint with
  • Grass for creating dioramas

Step 2: Prepare the soil for grass

Step 2: Prepare the soil for grass

Take a piece of Styrofoam and cut it according to the size you want your grass shape/diorama base to be.

Color your model or shape the color you prefer. If you wish, you can make it appear like the colors of the earth.

Step 3: Paint glue on the places where you want grass

Use the paintbrush to apply glue to your model. The more you spread out, the thicker will be the grass blades and vice versa.

Step 4: For fake grass, use an applicator

Step 4: For fake grass, use an applicator.

You can use an applicator, paintbrush, or your hands to apply the fake grass. Just sprinkle it over the glue and let it dry for a few hours/overnight. You can also spray some adhesive on it after applying to do not fall off when handled roughly.

Step 5: Yellow grass should be used to line walkways or roads

Yellow grass also helps to make the diorama look more natural.

Step 6: Puddle & Water Effect

With hot nails, you can make a perfect puddle effect; just apply glue from the gun to desired locations on your diorama.

I know it sounds rather scary, but nothing could stop me once I learned how simple they are and all of their possibilities for creating amazing things with water-based adhesives like silicone (which has its own set of perks)!

Step 7: Apply the glue again

Put glue on the routes where you will have walkways.

Step 8: Put dirt on the ground that people will walk on

You can also color the earth with brown paint if you want it to look like natural mud or soil! Avoid using too much glue; otherwise, grass blades will be thin and spread out unevenly. Also, remember that more oversized shapes of models give rise to thicker grass blades than smaller ones.

Step 9: Other things, such as stone, moss, bark, and wood, can be added to make your diorama more realistic

Step 10: Let it dry overnight or for a few hours

The grass will take some time to dry after application, so leave it overnight or for a few hours before moving on. If you are using hot glue guns, they should be fine even if left out in the open but otherwise, use small tools/parts and let them sit undisturbed until everything is dried up well. Be patient!

Tips and Tricks For Making a Diorama Look Realistic

  • Add textures like moss, twigs, and branches to make the background look more realistic
  • Make rocks out of clay or craft foam for a natural feel
  • Use seeds to make lifelike grass
  • Water down the paint so it looks more like natural light
  • Use color to add details like cracks or lines for a more realistic look
  • Use twigs and branches to make trees for a little more detail
  • Try using large rocks as mountains or hills
  • Add animals like lizards, snakes, or birds for some extra color
  • Draw up plans on paper before you start painting so you can get the colors right
  • Use a circular pattern for the grass or diagonal lines to make it look more natural
  • Add some texture with paint, like moss on the rocks and bark on the trees.

FAQs

How do you make tall model grass?

There is no unique trick involved when trying to make tall grass for dioramas, just cut the blades of your material with scissors and glue them down one by one in a line. Alternatively, you can also use ‘flock’ type materials which are more suitable if creating shrubbery/bushes, etc. However, I personally find it takes too long to apply individual length grass to models!

How do you paint fake grass?

You can color or prime plastic/cardboard before applying adhesive over it (although this isn’t always necessary). If using natural plants, remember that they might get ruined from any chemicals used, so try testing out some paints first on samples made from other types of material! I recommend using a light brown color for the soil and glue before adding paint over it with artificial growing lawns. Just mix in some white or other colors into your paints to add more variation if needed!

How do you make model train grass?

You can use the same method as making model grass, except you will need a mold or a template to put over your material, so it’s all even. You should also try adding some pigment into the glue before using it on cardboard/plastic, just like regular plant growing materials!

How do you glue down model grass?

To glue down model grass, you will need to use ‘thinner’ adhesives for this kind of material. It is also a good idea to use tweezers or another tool that can help pick up individual blades! Thinner glues are best since they dry quickly and allow corrections if needed (e.g., accidentally picking up too many green pieces).

TIP: Try not to overdo it with the adhesive as there might be some chemical reaction between materials that could ruin everything! Also, make sure you do any tests first before actually putting your project together just in case something goes wrong along the way!

Conclusion

The grass is an important component in the diorama and it can be made with a few simple steps. You will need to gather your materials first, such as paint glue or a fake grass seed applicator if you want to use real grass. The next step is to prepare the soil for the grass by adding water and dirt from outside sources. Once this has been done, make sure that there are no rocks inside of it before applying different types of vegetation onto the ground where people walk on. This will provide a realistic effect when looking at your finished project!
