Preparation and Safety Guidelines

Tools Needed
  • Cellulose sponge (green or desired color)
  • Floral wire
  • Green paint (or desired color)
  • Brown paint
  • Wire cutters
  • Wire strainer
  • Cheap blender
  • Bucket
  • Two sets of pliers or a drill
  • Super glue
  • White glue
  • Tweezers
Safety Guidelines
  • Always work in a well-ventilated area when using spray adhesives and paints. Inhaling fumes can be harmful.
  • Use caution when handling sharp tools like craft knives or scissors. Always cut away from yourself and supervise children.
  • Dispose of leftover materials responsibly according to local regulations. Some paints and adhesives may be hazardous waste.

Step-by-Step Instructions

  1. Prepare Ground Foam Mixture

    • Add water to the blender, tear up the sponge, and pulse blend until you achieve a desirable consistency.
    • Incorporate paint into the blended sponge mixture and blend continuously until well mixed.
    • Use a wire strainer to remove excess water, squeezing out as much liquid as possible.
    • Let the strained mixture dry completely in a cardboard box. Drying time varies.

  2. Create Tree Trunks

    • Cut floral wires to your desired length and twist them together using pliers (or a drill) to form the tree trunk.
    • Bend the wires into branch shapes and trim to your desired lengths.
    • Apply brown paint to the trunk, dabbing it on rather than brushing to create a textured look.

  3. Apply Ground Foam to Trees

    • Use super glue to securely attach the first layer of ground foam to the branches, using tweezers to handle the foam.
    • Use white glue to attach the remaining foam, adjusting and shaping as needed. Let the glue dry completely.

Tips

  • Don't use your kitchen blender for this project; use a separate, inexpensive blender.
  • If adding more paint later, avoid adding extra water to maintain the desired consistency and color.
  • This method is ideal for creating custom hero trees, not mass-producing trees.
  • The resulting ground foam is versatile; use it for various scenery elements like bushes, brush, and ground cover.

Common Mistakes to Avoid

1. Using the Wrong Sponge Type

Reason: Not all sponges are created equal. Some are too dense, resulting in a stiff, unrealistic ground cover, while others are too soft and lack the necessary texture.
Solution: Choose a relatively firm, open-celled sponge that holds its shape well but remains somewhat pliable.

2. Insufficient Paint Application

Reason: A thin, uneven coat of paint will result in an unnatural, patchy appearance, lacking the depth and variation of real ground foam.
Solution: Apply multiple thin layers of paint, allowing each to dry before adding the next, and use a variety of shades and techniques (dry brushing, sponging) to build texture and realism.

3. Ignoring Texture and Detail

Reason: Smoothly painted sponges lack the visual interest of real terrain. Similarly, poorly designed trees look unrealistic.
Solution: Add texture using techniques like stippling, dry brushing, and applying additional materials (sand, flocking) and carefully sculpt and layer your tree branches for a natural look.

FAQs

What kind of sponges are best for this project?
Regular cellulose kitchen sponges work best. Avoid abrasive scouring pads or sponges with pre-applied soap.
What paints should I use?
Acrylic paints are ideal as they dry quickly and adhere well to the sponges. You can use craft paints, model paints, or even diluted house paints.
How do I make the trees look realistic?
Use different shades of green and brown paint to create depth. Consider adding small details like lichen or moss (real or craft versions) for extra realism. Experiment with different sponge shapes and sizes for varied tree types.
