Homemade telephone

On Sunday, I made a telephone, using a ruler to make a handle, a paper balloon to make a receiver, another paper balloon to make a microphone, and a white cardboard to make a landline.

I first inserted the ruler into two paper balloons, then drew a display on the white cardboard, and finally drew the number keys and symbol keys under the white cardboard.

My phone is ready, do you think I am doing well? Please comment on it, ok?
