Is this a good idea to make money?

so im pretty new to knitting (i know the basics) and i can now make things with pretty much no mistakes. do you think if i made blankets and sold them on ebay or something if i can get a little cash? im just a teen who needs a small side job. More like a side project, and it'd be nice to do something i like, and yet get money for it. so what do you think?(:
