When installing in-wall speakers, use a drywall saw to cut the hole. A utility knife will make the cleanest cuts in drywall, but a utility knife can be difficult to control by a non-expert. Electric rotary saws make cutting drywall physically easy, but they too can be difficult to control. A simple, inexpensive drywall saw (about $10 at your local hardware store) is the best bet for beginners. The speaker's frame will cover up any rough edges.
Most bulbs, including tulips and daffodils, should be planted with the pointed end up-this is where the leaves will emerge. Small, round bulbs can be planted in any direction. If in doubt, plant bulbs on their sides. This will make it easier for the leaves to grow up and the roots to grow down than if the bulb were planted completely upside down.
