I had some spare black coro in the garage along with some modules from a failed first attempt at a candy cane. I don't call them mistakes, I can them design changes. So I decided to make a Bethlehem star tree topper. It will have 8 separate sections with dividers between them to separate colours. Have white coro on the edges and top and as many modules as I see fit in each section. One thing that I found works great is posca paint pens. I was using permanent marker to mark my cut lines but it's hard to see on the black coro so I tried the paint pen. Worked great and you can scratch it off with the edge of the razor blade too in case you make a mistake or need some construction lines. The star is 900 wide point to point and 1200 high.
