Tieing on a new warp.

I've never done this before, but I'm hoping it will work. I intend to weave another rug using the same tie-up/threading etc as the last, only in different colours that will surely use up the last of my pre-dyed weft yarn. I'm following instructions for tieing on a new warp onto an old warp, from an old "Handwoven" magazine - I will report back on progress, if progress is made.

And while some industriously follow their hobby, others just lie about by the fire.
