2 things to consider as well. What is your cost in materials. What is you time worth.
(You will never make a living selling what you make alone, because you can't make enough, fast enough.) Another consideration is what part of the country are you selling in (I see you live in California.) Are you targeting everyone or a specific age group. If it's washable and over 18 inches (not including the tail) I'd put it at $45.
But remember to have fun!!!!
