Download the PDF file and print one copy using Letter or Legal paper size. Using Legal size you may expect a sphere around 15cm radius. Add 5 white/colored sheets of paper below the pattern and cut them up (use some tape to keep the sheets together). You should complete 6 female modules and 6 male modules.
Step 1: Overlapping Modules
Start by coupling one female and one male module. Start by the center and overlap the curves so the 'less curved' are placed inside the sphere and the most protuberant ones are placed outside the sphere. Cut some small tape squares to place right in the vertexes. Once all vertexes are joined together it is going to look like two slices of orange, 1/6 of the whole sphere surface.
Step 2: Keep It On..
..till you add all the 12 modules. Have someone help you by the time you are to close the sphere.
Step 3: Candle It.
