Anna also devised this bubble pattern with open spaces. The first 2-d picture looked a mess because of the holes. The picture would not show the cone’s transparent qualities. I had to put a solid cone inside to make it look less confusing. The close up may indicate the 3-d effect.
The cone is easy to weave because the circles of the two parts should be lined up as you go along. You may even glue them together from time to time while you weave to fix the vivid strips. In the last part you omit weaving to get the monochrome top edge. Take care not to glue too often near the top. This may force the strips into unnatural angles causing creases and wrinkles when you line up the top edge.
