Okay, so first things first, you'll need a frame for the fireplace. You can use cardboard or wood for this, but it needs to be sturdy enough to support the weight of the decorations. Next, you'll need some fake logs or bricks to give it that realistic look. You can find these at any craft store. Then, you'll need some lights to make it glow. You can use string lights or Christmas tree lights, but be sure to test them out first to make sure they work. Finally, you'll need some decorations to give it that festive feel.
