Welcome Kaela to Beading Daily!
I checked out your website and you are doing very well to have just started! I don't sell really but hope to eventually just to be able to buy more stuff! And YES it gets very expensive and I think most of us fell into the "inexpensive hobby" idea with beading and boy were we wrong!
This site offers plenty of good info and there's always the forums to ask for any help you may need with anything.
Hope to see you around often!
