Wrap on a raised warp...

James always told me, "advancing color wraps on a raised warp"...  (Frequently followed by, "why aren't you doing that?").

I am teaching a class at Intermountain Weaver's Conference next weekend (if you're interested there is an unexpected opening or two) and in preparation for this class (Color Gradation for Tapestry) I did a sampler in the hope that my explanations about hatching and hachure would be a little clearer than mud.  Since I chose two very contrasting colors to illustrate the hachures we are going to be learning, the results of not wrapping on the correctly oriented warp thread were extremely obvious.  I just wanted to share this graphic illustration...  And yes, I do realize that you're only going to get a charge out of this if you're a tapestry weaver... and possibly not even then.

This photo is from the back of the weaving (the side facing me as I was weaving).  I weave all my tapestries from the back.  I don't want to get into why right this moment.  I just do.  Wrapping an advancing color on a raised warp yields this bumpy hachure.
But magically when you look at the other ("right") side of the tapestry, it looks like I drew those angles with a straight edge.  Cool, eh?
Yep, I'm a bit of a weaving nerd.

  1. It's a great trick for smoothing angles and curves. It your rising unevenly on an angle you can also add a one warp twist of soumack to make it right or run a half pass down the angle or curve to smooth and change the hills and valleys.
    There is also something called Jan's law to smooth angles and curves. It's to always rise on multiples of two.
    James was a good instructor.

  2. What's the definition of advancing color? By the way, love the skaters' costumes, especially the fishnet stockings.

  3. Sherri--That was referring to something like hachure, though it can apply to any shape. When one color is advancing or moving over a color below it and you are going to continue to move the color in that same direction, if you don't wrap on the raised warp (if weaving from the back), you'll get the jagged lines like in the top example instead of the smooth ones in the bottom example. Holds true for the bottom or top of forms that are fairly flat too. I'll post a better photo when I get back from this conference and have my computer available again.
