Hi, Im new to this site and it really seems real useful for beginners that want to start a custom t shirt company or just make thier own. Just dropped out of high school and trying to get my GED and enter a TECH school to learn more about graphic designing.My dream is to be making hot urban shirts like for models and hip hop. Still stuck on what school to go to for good learning of graphic designing
I have a few questions i could use help on and your thoughts on my work.
1. For my first question i would like to know if when working with adobe to make a design what would be the required size for the design so it can fix in a t shirt
For example this work in progress
This picture i would want to be like the photo below
Its like those t shirts that have like some kind of paper photo like some Biggie and 2pac shirts if anyone have seen. And what format does the picture have to be to be custom on a t shirt, like does it have to be JPEG or it doesn't matter

This photo like the cloest i can show of what i want it to be.Couldn't find those 2pac shirts like it.I would want the design above to printed on something like this example shirt.What would a good size for the design need to be for a shirt like this and where would it be good to go to have it made. Im from Clifton,New Jersey. So anywhere near would be good.

Next for this next design im working on.What would the photo size would need to be to like that would be about the same size as the picture below

example i would like the picture above be like

Hope all this made sense, just trying to learn
Any feedback on my work and questions would be really useful. Also if have any ideas on improving my pictures would be nice.
