Step 1: Find the picture you want on the internet and draw it on graph paper. Then decide how big you want your doorhanger to be and scale it up by drawing a grid on your material of choice (this is PVC board). Or if you're real fancy, use a projector instead of the grid method. Either way works.
Step 2: After drawing your doorhanger find a jigsaw and a man and have him cut it out. Or you can do it yourself but then you couldn't take pictures of the process. Which is obviously a very important part.
Step 3: After you've got it cut out, use a file and sandpaper to make the edges smooth. If you use PVC board, you'll also want to use some fine grain sandpaper to sand the surface you'll paint. This will help to keep the paint from coming off.
Step 4: Sketch your lines on the doorhanger for reference when painting. Or if you're a real badass, skip this step and go straight to the painting part. As you can see, I am not a real badass.
Step 5: Paint.
Step 6: Keep painting. Try not to cry when you get it on your shirt (why are you wearing a good shirt to paint in Kalyn?!) or when you mess up a little bit.
Step 7: Wait a day or so for it to dry, fix any minor details, paint the edges, and spray with a clear coat to protect it from the weather.
Step 8: Buy a house to hang your brand spankin' new door hanger on. I haven't finished this step yet, but hopefully that will happen soon.
Step 9: Decide if I want to sell door hangers to family, friends on facebook, etc (opinions?).
