I am planning to do a design in photoshop and i was wondering, how big the document should be that i am creating.

the template is to small, it's 72dpi anyway and ~22cmx22cm (sorry, i'm european, using the metric system).

so... somewhere is mentioned to make sure to work with at least 150dpi.
do you use an document with -let's say- 30cmx45cm in an even higher resolution..?

or should i just skip the pixel-thing and go on with vectors and do it in illustrator? :D (just to avoid the resolution/size-problems)

(i'm afraid, this is a stupid question)
thanks for the help!

i just love it.

was browsing through comments and users and finally got to this t-shirt.

i love the design. i need this to be reprinted!
maybe in another colour.
but vote, people, vote for it.

i just love it!

Crazy, i bought the hoodie.
Without having seen a picture of that yet.

and i broke my golden rule: don't wear white jackets/pullovers/pants. (to sensitive for me...)

but that one is sooo cool :)
hope it's also cool as a hoodie.
post a picture when it has arrived.
