It has been five years since I made a circle a day, and ten years since I made a fabric postcard a day. Time to do it again.
I am starting with equilateral triangles, and the color green. The triangle above is 3.75″/10 cm on a side. The nice thing about equilateral triangles (all sides equal) is that they tile smoothly on a flat surface, and they can be used to compose three dimensional shapes. I am going to have a lot of these triangles – I should be able to amuse myself with the results when I am done!
