These trees have been popular since the 1970's or 1980's. We use to make them many years ago when the pattern first came out. Donna Jordan's Christmas Tree Napkins that are so popular now we're first seen by me almost 15 years ago in St. Charles, MO. Someone had made copies of the instructions on a 8 1/2 x 11 inch sheet of paper and they were passed out at the cash register. What's old is new again!!
