: I think I've still not been clear about what "warp take-up" means--although I'm not sure that any of you should care!!! But here's a concrete example: If a rug 5 feet long actually required 5'4" of warp there would be 4" lost to "warp take-up." On a balanced-weave fabric there will always be some warp take-up (since both warps and wefts are slightly wavy), while on a weft-faced fabric there will be none or almost none. On a warp-faced fabric there would be considerable take-up (since the wefts are straight and taut, the warps are the only wavy elements), and a weaver who wants a finished fabric of a specific length needs to add a little extra length when preparing her warp.

: None of this, of course, has anything to do with the extra warp length needed for tying onto the loom's front beam or for heddles and shed stick space at the other end of the rug.

: Since this kind of thing rarely needs to concern non-weavers, it is not something I've gone into in the book, although I have explained how weft-faced fabrics and depressed-warp rug structures are produced. Anyway, just to be clear, "warp take-up" is purely a weaver's concern and is NOT a necessary or appropriate part of any carpet analysis..... How did we get into this anyway!!!?

Marla,

You say that warp take-up is only the weavers concern and not part of carpet analysis. Could warp take-up explain some rugs in which the design elements appear to have been not very well planned? Many rugs, particularly village and tribal rugs, look as though the weaver did not leave enough room at the top to complete the design properly. It is as though there should have been enough warp to finish the design, but it stops abruptly at the top of the field. I think the common explanation is that this indicates that the design "continues into infinity" beyond and under the borders. Perhaps it could be lack of proper planning?
