Mushroom

I made this little mushroom keychain the other day, actually I made a couple as I'm trying to sell them at a craft fair. This weekend will be my first time going there so I hope everything turns out well, and I actually sell some of these. I'm thinking of pricing them at $4, but I'm not sure if that seems excessive, or not enough? I have some other ideas of things I can make, but haven't had the time to make them.
