Jelly fish illumination

Light and lampshades are a speciality. Simple tentacles with pearly tips. Guess ? here's a clue : the individual tentacles were used to mow a small lawn. I purchased them in bulk from a well known discount store ( alas they no longer sell them) and the man behind me in the check out queue had the impertinance to comment " You have a lot of bikinis". I replied," No sir I'm making a light shade".
