STEP 2: Hot-glue plastic bugs to the wood — making sure the decorations are small enough to fit inside the glass when you seal the terrarium.
STEP 3: Spray-paint everything but the jar — twig, bugs, lid — white or black.
STEP 4: Once the piece has dried, hot-glue green floral moss around the base of the twig. Carefully place the jar upside down over the lid and screw it on.
To make the crow version shown, follow the instructions above, but hot-glue a fake bird to the twig after you spray-paint.
