This pattern was a challenge issued by me to my teacher, as her class were all working tape lace christmas trees. I work most of the time with Bedfordshire lace and wanted a Christmas tree in this type of lace, and so she designed one for me. Then the challenge was passed back to me to work out how to work it, and this was the result.
The pattern is worked twice, stiffened and folded to right angles and then when dry joined together to form the 3D tree.
