What to use to pattern

[t_eagen13]

What does everyone use as a target when patterning their shotgun? I've used cardboard from boxes before but I don't have much and was wondering what everyone uses? I'd like it to be big enough to see most of the pattern so I can see if I need to adjust if the point of impact is off. Thanks!

I buy the roll of paper from Lowes, Rojo Roll it is called.  I can't find in on the Web site, but it is the only thing available from my local lowes.  Here is the same thing, just brown.
