Good luck on your venture into the business world, Tiff!
But...$5 or $10 seems awfully cheap for handmade scarfs. Don't sell yourself short. I don't know how you make them or how long it takes to make one, but, and this is just my opinion, you ought to figure on making $15-$20 an hour for your time, maybe more.
On the other hand, you know what you want to do, so go for it!
