Prop halves of plastic bunny up on plastic cups on a large piece of cardboard. Using 2-3 light coats, spray paint both halves brown, making sure to paint the "lip" around the edges as well. Also paint the piece of scrap wood.
Allow bunny to dry thoroughly.
Push the halves of the bunny together. Use paint pens to draw on eyes, nose, and whiskers if desired.
Use plenty of hot glue to glue the bunny to the piece of scrap wood to act as a base.
Place the bunny inside the basket. If the basket is tall, you may want to set it on another piece of scrap wood or another item to raise it up so the bottom of the bunny is level with the top of the basket. Fill the basket with Easter grass to cover the base. Tie a ribbon around the bunny's neck. Add Easter eggs if desired.
