By the way, if your finding it hard to find legal paper, just pick up some A3 paper, cut it to the same width as A4 (when portrait).
You have yourself some make shift legal sized paper! I had a ton of A3 paper lying around...
So if its cheaper to pick-up the A3, as well as easier, just do that....
A lot of wasted paper, but when you really want to print out covers, that should be a non concern.
