An easy to find glass bottle for this project is the bottle used to hold a product called Panax Ginseng Extractum. Look for them at your local health food or liquor store.
It is easier to get the hang of covering bottles with beads if you don't have to deal with a pattern, so we are not going to use one. Instead, we will use a mixture of colors and sizes in a freeform design made up as we go along.
First empty the bottle, rinse it and soak if necessary to remove the label. I used my bag of mixed seed beads (a mix of small amounts of seed bead leftovers from other projects) for this project. If you don't have a bag of mixed beads, just choose several colors that you think would look good together. There are two ways you can go with this. Either choose a selection of colors that harmonize with each other such as a range of blues, for example, or colors that contrast strongly.
