Weeks Dye WorksA hand over-dyed, six strand cotton fiber. Because it is pliable, this fiber is perfect for cross stitch and needlepoint on many different counts of fabric and canvas. It also works great for punch needle and stitching on wool applique. Weeks Dye Works recently changed their dyeing process so that most of the currently available fibers are colorfast. They did this in an environmentally responsible process, and are currently color fasting all of their floss colors, but haven't quite finished.
