This is a multi-purpose pattern because you can extract a shawl from the instructions or continue on to transform the top down triangle into a rectangle to make either a poncho, pullover, ruana or other kind of wrap. This pattern includes detailed charts, schematic, supplemental video tutorial and written instructions.
