Hanging on your chest? I'll teach you the simplest one. First find two long asparagus in a circle, the size is up to you. Prepare Cymbidium hybridum, Cymbidium hybridum and green silk, cut Cymbidium hybridum piece by piece, tie Cymbidium hybridum and Cymbidium hybridum together with green silk, and tie it to asparagus, that's all. Note that orchids should not only be tied on one side, but should be everywhere like flowers.
