How can you know what "Three Jewels" is in various languages ? Things change during the course of centuries, gradually, and inevitably. Maybe the ethiopian robe is also inspired by the famous indian person Gautama and His followers ?
The Buddha's robe looks as made of one piece in many ancient statues and pictures.
I hope you do not mean to say that the robe has blessings if a new fabric is first cut to pieces and then stitched together!? -imitating the original ascetics who wore a robe made of castaway clothing!?
Buddha does not say in the Karuna Pundarika sutra that it will be a Vogue model of stitched-from-rags robe that has the exact & right number of squares in it.
In the beginning period of Sangha the robe was certainly a symbol, or a sign, for all ascetics or left-home people in general.
Idries Shah tells us that a robe made from pieces of cloth has been used by Sufis in North Africa for centuries. I noticed in TV that Gaddafi wore a green robe draped over his left shoulder when he was giving some important messages to his people, quite recently.
