Toy Workshop

You own a toy making studio with two employees. Carving a toy takes two hours. Painting one takes one hour. Packaging one takes one hour. You cannot paint a toy until it has been carved. Similarly, you cannot package one until it has been painted. Both of your employees are capable of doing any of the three tasks, but they cannot both work on the same task for the same toy at the same time. What is the lowest number of hours it would take your employees to carve, paint and package three toys?
