Greek gifts - iron-on letters - craft items

It's chilly outside, the Christmas music is on and I just made my daughter's letters and sewed them on a t-shirt and made her shorts to match the color of the letters on the t-shirt. Now I think I want to do the same for her Big and for her roommate as Christmas presents. (My daughter and her roommate rushed together this past fall and now they are sisters, too). I can easily make the 3 letters of the sorority but I would like to have the whole name on the back. Where can I find things like Greek iron-ons and greek fabrics and other greek craft type items?
