Box with Woven Triangles XIII (corrected)
When folding this box, I thought I was making a clean fold of Box with Woven Triangles XVI (previously in error labeled number I), but I missed one detail and ended up with yet another design. You can tell the difference between XVI and XIII by looking at the edge between the box’s top and side walls. This nicely shows one can get lost even in one’s own designs with good documentation, not to mention other peoples’ designs.
