This depends upon how creative you want to get with the weed that you are going to be smoking. You can choose to cut holes in your joint from the sides and stuff in other joints into them to add more parts to a joint and then stick them up well, giving them a proper shape. Some people get really creative and create shapes like a candelabra, a christmas tree, a spider, a cross, etc. It allows you to pack in more weed and is something you’d generally like to do for a special occassion or a gathering.
