Well i have both, and im poor too.
Simply apply a material by going in the material section(load one up, whether it is blank or not, if its a fresh unwrap, use a completly black picture), then select a group, go back to the material tab and apply it, then select a face and go up to the top menu (near the end) and go to the unwrap editor and unwrap there.
When you have done , open the unwrap veiwer/editor then screenshot, cnp that into your art program and draw in the lines, when you have done that apply that to the material editor and walaa!
although, im not a..like..smart so TDR or someone else will most likely whoop my ass cuz im sure im wrong somewhere..
sozz, im trying to remember this off my head.
