Gather a wheelbarrow full of evergreen trimmings. Some suggestions are cedar, pine, fir, juniper, redwood, oak, bay laurel and asparagus fern.
Cut the trimmings to a length of 6 inches.
Lay a 10-foot length of string or twine on a large, flat surface. Tie a loop in one end of the string.
Attach #24 floral wire - also called paddle wire - to the loop end of the string. Keep the wire attached to the spool and unravel it as needed.
Select several foliage pieces and place them together in a bunch, with the stems at one end. You can mix different kinds in one bundle.
Place the bundle of foliage at the loop end of the string with the stems pointing toward the long end of the string.
Wrap the floral wire around the stems and string to secure them in place.
Wrap the floral wire around the bundle twice and then pull it tight. Make sure to leave the wire attached to the string.
Gather another bundle of foliage and lay it so that the stems overlap the first bunch and cover the stems. Make sure that all the stems are facing the same direction.
Continue the process of overlapping the bunches of foliage and wiring them to the string until you run out of string.
When you get to the end of the string, twist the wire tightly around the last bundle's stems, and knot the wire and the string together. Leave 12 inches of wire (to attach the garland where you want it) and cut the wire with scissors or pruning shears.
