We made this card at stamp camp as well.
The blue background was treated with a heavy coat of Epsom salt and water…1 Tbsp of each heated in the microwave for 30 seconds. Stir until dissolved and apply to your paper! I love how it looks like frost. You get a different frosty look if you want to dry it with the heat gun. Be careful not to paint over your strokes, for some reason it removes what you previously applied.
Thank you for stopping by!
