A homemade Christmas tree card (or invitation or gift tag) that doesn't require special equipment or too much work. Use a lollypop stick (or something similar) as the trunk, ribbon as the branches and a gold star as the topper.
For a Mason jar gift you can make in bulk, try these easy candles. Wrap the jar with wide plaid ribbon. Secure with three jute strings tied in a bow. Hot-glue a pinecone and artificial greenery to the bow. Place a tall, slender pillar candle in the jar.
