Trim all faux greenery stems into 5-inch-long pieces using wire cutters.
Anchor the end of a spool of 24-gauge wire to an 18-inch wreath form.
Bundle 2 stems of greenery, and attach them to wreath form, winding wire to secure. Continue adding greenery in bunches, winding wire to secure, until wreath is complete. Cut wire.
Using the directions in Glowing Cups and Candlesticks, coat front and back of wreath with white primer spray paint and fluorescent-yellow spray paint.
To hang, make a small upside-down U from a piece of wire, and secure ends to the top back of wreath form.
