This little piggy (bank) started off at the market as a bleach bottle.
Rinse an empty bottle with hot soapy water; let dry. Cut features such as eyes, ears, and nostrils from construction paper (ears should have tabs).
Attach with double-sided tape, as shown. Tape patterned paper around body. Hot-glue empty thread spools on for legs. Cut a slot at the top for coins, and a hole in back to insert a pipe-cleaner tail.
