hi, we just did it for my nephews shirts for our Feb. trip, they are 2. depending on how your printer is set up you can do it two ways. when i click print i have print wizard pops up and it tells me to select the photo i want then i click next and it takes me to the screen with all the different sizes i can print. you will have to play around with the 4x6 and 5x7 because it sometimes cuts off part of your disign. if it doesn't fit i also can click print, select picture, then preferences and choose my size in that menu. when i do it that way it shows on the screen that it is printing full size but it comes out whatever size i picked and doesn't cut any of the disign off. i hope that isn't too confusing if it is just post again and i will check back later or feel free to pm me. good luck!
