How to paint flames on my wall?

alrighty, so i'm going to paint flames on my wall, and i'm not too worried about the color choice i've got that pretty much handled i can figure out the shading...but what i'm unsure of how to do is actually draw the flames on the wall. I can't seem to make them look right, on a bigger scale. I'm making the flames about 2 and a half-3 feet high, and the whole length of my wall..going horizontally so that's about 12 feet long. Any help would be awesome!How to paint flames on my wall?
1) Get it exactly right by downloading an image of what you want and modifying it in Photoshop or similar graphics editing program (copy, paste, crop, stretch, etc)





2) Next, if you want your tracing process to be easiest, in the graphics program do an ';edge-trace';, an emboss, or a negative (or some combination of the three) and make it greyscale or b/w.





(EVEN EASIER: some graphics programs have a ';colouring book'; filter to do #2 for you with one click)





You do not have to do step 2. I often skip it and just trace the image once it's enlarged, but it IS easier to trace if the outline is as clear as possible. It doesn't HAVE to be black and white, either.





3) If you have access to a LCD projector, project this new ';coloring book'; image on the wall and trace it.





~or~ if you only have access to an overhead projector:





3) printout as large as possible on 8.5x11 and then print to or photocopy to an 8.5x11 transparency ...put that on an overhead projector and shine it on the wall to trace. You want it as big as possible on the transparency so you do not have to place the projector very far back to make the image as large as you want. Even if you print it directly to special printer-ready transparency, have a paper printout to refer to while you work.





~or~ if you have only access to a slide projector:





3) printout and photocopy (or print directly) to a transparency, but do it the size of a photo slide, trim transparency, and use a slide projector to enlarge and trace to wall.





~or~ if you have NO access to ANY projector:





3) time to go old-school... printout on a piece of 1/2'; graph paper, or print a 1/2'; square grid over the flame outline printout. Caculate # of squares your drawing is wide. Let's say it's 6 squares wide, then, on the wall draw 2ft squares on the wall (2ft x 6 = 12ft wide wall) and then manually draw whatever is in each square on the paper in each square on the wall. This is the tried-and-true textbook method of enlarging anything 2D





Aside from just taking an image to Kinkos or similar, and having them make you a vinyl banner, this is how to enlarge anything you can put on your computer screen.
