I first painted the canvas with white paint and then added the letters that I cut out of vinyl from Cricut Explore machine. The vinyl DID NOT want to stick. I thought it was just the cheap stuff I was using so I used some better vinyl, but it didn't want to stick either. It took me more time trying to stick those letters down than it did for the whole project.
Here's a picture with the vinyl.
I probably should have left it at that, but it wasn't what I wanted for the end result, so I forged ahead. I added two coats of black paint and a few touches of the white to create a chalkboard affect. It looks better in person, but there was one area where the vinyl pulled up a little.
Here is a picture of the canvas at my sister's wedding.
Congratulations to my beautiful sister Michelle and my new brother in law, John.
