Create a Hannah Montana microphone with a paper towel tube, toy vending machine egg, tinfoil, a permanent marker and Hannah Montana stickers. Place the egg upside down over the end of the paper towel tube. Wrap tinfoil around the tube and microphone. Place a small piece of tape at the fold if it is not holding in place. Use a permanent marker to draw dots all over the top of the microphone. Place Hannah Montana stickers on the base of the microphone for decoration.
Make a Hannah Montana guitar with cardboard, Hannah Montana stickers and coloring supplies. Cut a guitar out of a large piece of cardboard. Have the children decorate the guitar. For a realistic effect, add yarn for guitar strings.
Print Hannah Montana pictures off the computer on to T-shirt transfer pages. Iron the transfers on to a T-shirt. Have children decorate around the picture with puffy paint. You can help the children write words if they can't do it themselves.
Cut a piece of material to fit around your child. Attach it to his Hannah Montana guitar with string. Ask the child to decorate the strap with puffy paint. You can write words or let him use glittery and shiny paint for decor.
