Use a stud finder when looking for wall studs. Don't rely on knocking. Don't hammer a nail directly into dry wall, it will come right out. Use a wall anchor if you're hanging something that isn't on a stud. Pay attention to the weight restrictions listed on the boxes of hardware, going over them could result in your things falling off the wall. If you don't have a level handy, you can use a golf ball or a glass of water to see if a shelf is level.
Different sized bowlsRopeHot glueFillers for decoration (apples, soap, seashells) Place your bowl upside down. Coil rope into spiral while adding a line of glue to each spiral. Cut the rope and hot glue the end of the rope to keep the bowl from fraying. Remove the bowl and let the rope bowl sit and take shape.
