I have just started a clothing line where we hand-dye garments (not tie-dye though) and add my design to the front (using heat transfers, not hand painted)!!
I took a look at your site (and noticed you are also using prostores) and it looks great!
I did get a blank page when I went to "policies" though and did not see any FAQ's (such as how long before you get your order, what about sales tax....just all the "usual" type questions. I also could not "click" on your links at the bottom of the home page.
Your prices are high, but I am assuming that you have set those based on selling in boutiques etc. and the fact that every item is hand-painted.
The pics on your site are nice and clear and the logo is lovely!!
