Start by rubbing the candle in the corners, along the edges, and in random places on the metal sheet. This will cause the sheet to resist the paint and allow us to achieve a worn, rusted look on our piece.
Cover the sheet with two layers of your base color.
I used washi tape to mark off my border and paint it.
I cut the text out of vinyl and applied the reverse image to my sheet to create a mask.
Next, I painted the letters and after it was dry, peeled the vinyl away. Some of the paint lifted off with the vinyl, because of the wax resist technique. Exactly what I wanted! I used a cloth to rub off more paint, then sealed my project with Mod Podge. I used the Antique Finish to give it an aged look, but you can also tint your regular MP with alcohol inks to get a similar effect.
For my bowling sign, I used the trace feature on my Silhouette to copy an image I liked. As above, I applied the vinyl to create a mask, painted, rubbed off paint in the corners and on the edges, and finished with Mod Podge.
