all you do is go to the button "designs by cuties" and clcik it at top righthand corner of home page. it brings you to the page with all designs by the members of cute and on the left side you'll see a button that says "uplaod design". just click it and fill in description, etc. and save and post. hope this helps a little.
Perhaps if you private msg some of the cuties that have designs posted in the designs by cuties they can help you! GL *
