Soak moss in a bowl of warm water for 10-20 minutes. Wring moss dry, and mold around your wire wreath form using your hands to shape.
Wrap floral wire firmly around the moss and wire wreath form, until the moss is securely in place.
Add succulent plants at the roots to the moss, with soil still around your roots. Be sure to tuck the roots beneath the moss. Secure in place with wire. Work your way around the wreath, until you are happy with the end product.
Work your way around the wreath, securing succulents all the way around, until you are happy with the end product.
Cut a piece of ribbon your desired length, so that you can loop it around the top of your wreath. Hang on your door from a hook or nail.
Notes
To care for your wreath, keep moist with a water bottle. Make sure the wreath receives some morning sun, but is in shade the rest of the day. Direct harsh sunlight will damage your wreath.
