Great point! I feel like since the shawl is so big and has to be folded so many times to be worn, so much of the design is lost anyway! That and I just get so hot wearing the shawls, even on a cold day.In theory, you could split the large 140cm into 2 halves but it will result in the design being cut in half.
The triangles on the other hand have a complete, coherent design.
