Quoting Lord Lego 436
w did you get it into comic format? Please tell me in one of my mocs (as a comment)
Sorry, but it's about my MOC so it'd be less SPAM'e to post my answer here.
I use MS Paint(which if you have Windows XP should be somewhere on your computer) and the backgrounds in the link provided.
