Every day there's some new term for me to look up and learn. Yo-yos? Off to google I go.
I saw a jelly-roll in a fabric store and bought it to send to my cousin without knowing what it was, except that it was beautiful fabric. There was a Japanese word on the package and I googled that but it meant something else, probably the brand or maker. It was on this board I became enlightened to many concepts. So thanks for your question - it helps me but I've no idea about your answer.
