I've never bought one, then thought, hey, I can make that! In about 30 minutes, you can make one too!
gather the end of the tulle ribbon together and secured it with floral wire to the two middle rows of the wire wreath. Then I gathered the tulle ribbon again (leaving a generous loop) and secured it with wire.
I continued to gather and loop. If the looped tulle ribbon became too loose (I slid it closer to the last secured area) I secured it to the floral wire used for the previous enclosure.
