I started with this dirty rough pizza peel. The peel was covered with baking soot. I wiped it down with bleach water to get most of it off the peel. I weighted the board down so as it dried it would not warp.
I used the Typography Coffee Sign from The Graphics Fairy. I used the enlargement method to get the sign big enough for my project. The Graphics Fairy has a section on the different ways you can transfer her free graphics. Her graphics and information are invaluable!
After enlarging the image, I taped it onto the pizza peel:
I then used a pen and pressed hard onto the paper to outline the lettering. (It's a big graphic, I had to bandage my thumb from the blister forming <hint>)
I peeled back the paper and used chalk to help see the outline from the pen markings:
After I finished tracing the sign I used chalk all over to highlight the graphics:
I used a pencil to trace over the pen engraving; then filled in the letters with a black sharpie. I wiped down the peel with a sponge to get rid of the chalk. After it dried, I used a rough grit sand paper to "age" the graphic. I finished with rubbing lemon oil all over the pizza peel.
