Dear Mrs Rosta

I saw your advert online yesterday. I wonder if you could answer some questions .
       Firstly, can you tell me how I can make my own T-shirts? Can I send a picture from a magazine or can I send you a photo by MMS?
        Furthermore, could you please inform me how much a T-shirt costs? You say that your prices are amazing,  but do they change according to the size and material or not?
     I look forward to receiving more information from you so that I can send you my design.

                                      Yours sincerely,
Nikos Kokkinos
