An easy way to decorate outdoor trees that will benefit wildlife too, is to make a fruit garland.
oranges cut in 1/2 inch slices
apples cut in 1/2 inch slices
cotton string, 3 feet long
large sewing needle
Directions: Put the cotton string on the large sewing needle and make a knot at the end of the string. Put the cranberries, oranges and apples on the string to make the garland. Alternate the different fruits to make your own design. Attach the garland to tree branches. Be careful not to injure the branches by tying the string too tight. Remove the string from the tree when the fruit is gone, to prevent girdling the branches later.
