At the Monroe seminar, Diana Berns demonstrated the 1-hour prayer shawl technique. Basically, this:
Set two needles at left of bed to working position and one needle a distance away (for fringe). E-wrap cast on and hang weights. Knit, increasing one stitch on right every two rows. When you reach the width the shawl should be, set the carriage for hold and hold one stitch on the right every two rows. When you are back down to one stitch, start putting one needle back into work every two rows. When you reach the end, start decreasing one stitch on right every two rows. When back down to one, cast off one stitch. Block before or after "unworking" the fringe.
I did this with a cone of my all-natural yarn. Decide the angle was too narrow on a stockinette stitch. Thinking about embellishments, perhaps an Iriquois-insprired woodland theme? Or perhaps a Spanish Mantilla?
