Flowers on Canvas - everything purchased from Michaels. Glue flowers with fabric glue onto canvas. Use multiple coats of white spray paint depending on the look you're going for. White acrylic paint (not watered down) works for those tough areas that won't take the spray paint. Choose *white* fake flowers if you are wanting a completely white look, as the darker colors will still show through the white spray paint.
