Framework is not just another triangular shawl. Mercedes Tarasovich-Clark‘s pretty wrap, part of Free-Spirit Shawls (Interweave Press, 2013), has a third panel for more wrappability. Here’s a bit of the intro:
Mercedes… wondered what could be added or taken away from the shape to create something new. In this shawl, the triangle is both reduced, by casting on for flat-topped panels of lace, and expanded, by bringing in a third panel to make a longer wrap.
The shawl is worked in Quince Tern/Kelp.
