Cut wire to desired length. Pierce the wire into the center of a cranberry. Continue threading berries, bending wire into various shapes as you go. Bend end of wire into a loop, and wrap completed wire around candle, base of candlestick or other desired objects.
If desired, alternate cranberries with other items like wooden beads, acorns or pinecones. (Make a small hole in these items with a thumbtack or power drill before threading. A very fine bit should drill a hole just wide enough for the wire to pass through. Place paper towels on the work surface to catch debris. Use pliers to hold the item securely at a slight angle rest the pliers against the paper towels temporarily so the drill can "bite" into the item where desired. Raise the pliers from the work surface so the drill can get through.)
Dispose of garland after a day or two, before berries get soft. To prolong the life of the garland, try spraying shellac on the cranberries after stringing them. To avoid staining, do not place the garland directly on lightly-painted surfaces or linens.
