Muffin Tin Advent Centrepiece For this upcycled Advent decoration, you will need a muffin tin with twelve hollows, clay, a hot glue gun with glue sticks, four red Advent pillar candles of different heights, four red mini poinsettias, secateurs, moss, pine greenery, cones, and Christmas decorations such as small baubles and golden mini cones. You may also need florists' stub wires to attach the decorations. Step 1: Half-fill four of the twelve cups with clay and place the Advent candles in them, pressing lightly. tep 2: Carefully remove the mini poinsettias from their pots and plant them in four more wells. Step 3: Cover any visible soil and clay with the moss. Step 4: Fill the remaining four hollows with moss and decorate any space between the candles and poinsettias with the pine greenery. Step 5: Decorate your arrangement with cones and Christmas decorations. Tip: If necessary, fix them in place with hot glue or stub wires so nothing can move. Place your DIY Advent decoration in a bright, warm spot away from draughts. Water the mini poinsettias regularly from above with a small amount of water. Make sure they don't get waterlogged.
