Changing the TE artwork?

Hey guys! Seen a few posts on here about creating your own art work and the templates for them. I’m curious how you’d go about changing the TE artwork thats aleady on it. I understand that I’d need to make a psd file of the work, but I’m not too sure were you go from there? Thank in advice for any input.

after you get the PSD created, run to kinkos or office depot/max or any store that can print.

from there, print with 11x17(i think) cardstock.
or, if you have plexi, i’ve found that printing on photo glossy yields better colors and there is texture to the print.

Thanks for the link Raoul, thats what I’m looking for!
