What is the best way of drawing backgrounds wider than one frame?

Create a new "background" project with the wideness you need. Draw your background in it.
and then in your animation project import the background using the keyframer.

it has been explained in much greater detail elsewhere on this forum. for instance here

You can also simply use the "hold" option =)

gunnars question sucks

make your project wider (the wider background as new project's size),
then make your Frame with the camera tool.

now, you have 3 answers, help yourself and choose the right one !

Thank you, nothing is difficult with such wonderful descriptions
