How much should I charge for plushie commissions?

Charge with what you're comfortable with and what you think people would be willing to pay.

Think about how much your materials cost, think about the minimum you would want to be making per hour on these.

On average how many hours does it take you to make one, three hours? if you want to make $10 an hour for these then charge $30 plus a couple bucks for the price of materials, so maybe like $35 or a little more.

If you feel like that's kind of steep then I recommend you add a few details to make the item more special. You could add in some eyelashes, blush spots, maybe three little hairs on the tips of the ears. These are things that are easy to do but will add apparent value to the item.

Also, remember, do not deliver the item unless you are sure that they are ready to pay. I know this may be your friends, family, and classmates or coworkers that are offering to pay you and you don't want to think that these people would intentionally rip you off. However, once the person has the item in their hand there is less incentive to get the money to you. It really just makes it easier for them to forget and things can get awkward with you chasing them for payment.

So hang on to your item, ask the person, "Hey, I finished that plushie you asked for! Can I give it to you tomorrow or do you need some time to pay?" or say, "Will you be ready to pay tomorrow, I can give it to you whenever you're ready."

Also, if you package your item nicely (you can just put it in a shiny plastic gift bag from Michael's and tie the top with a ribbon) and include a personalized little tag or something, and a bill for payment, this will make you look more professional and people will feel more comfortable/obligated to actually pay you.
