Here’s where patience is key. Concrete needs time to set—usually 48 to 72 hours, depending on how humid your space is. I know, waiting is the worst, but don’t rush it!
Once it’s fully cured, peel away the cardboard. The moment of truth! I made a batch of these, and while some had tiny imperfections, I actually think it adds to their charm. If yours turn out a little uneven, just display them strategically (aka, put the wonky side facing the wall).
