Please help

Hello All!!! I need your help... I'm trying to use text to create something, but I do not want the white background. I'm going to create some tshirts for work using pages and preview. Everytime I upload it onto the tshirt's website it still has the white background. Do I need to download something for this?? Please help, time is critical. Thank you all!!!

I use iDraw for this type of thing, available from the App Store.
I can't see a way of turning off Pages white background.
