Information about our bulletin sample submitted by : Pat Zannier
Thank you to Pat for submitting and writing the article and to Nancy for weaving it!
A
regular twill, i.e. one without skips, is a good basis for a Shadow
Weave draft. For this sample, the Atwater Shadow Weave method was
used. This works on the principle of using a DARK end for each
thread of the original draft. Accompanying each DARK warp is a LIGHT
end which is threaded on the opposite shaft. (Opposite of shaft 1 is
shaft 3; Opposite of shaft 2 is shaft 4, opposite of shaft 3 is shaft
1, opposite of shaft 4 is shaft 2.) Here is the original “M&W”
twill threading, woven as drawn in:
Following
is the above twill draft re-written. The DARK ends follow the basic
draft, with the addition of an extra end at each reversal or turning
point, plus an empty space is left between each DARK end.
The
next step is to add the LIGHT ends. First, determine the direction
of the twill line, either ascending or descending (see arrows over
the draft). The LIGHT ends are inserted on the opposite shaft of
the DARK end, but will precede or follow the DARK end according to
direction of draft. Use this chart for placement of LIGHT end.
Note, dark is always
the same as original twill draft, the LIGHT ends either precede or
follow the DARK ends:
LIGHT DARK LIGHT
DESCENDING ORDER ASCENDING ORDER
(light end precedes dark) (light end follows dark)
3 1 3
4 2 4
1 3 1
2 4 2
Adjustments
at turning points: First, an extra DARK end was added at each
turning point in the original twill draft. To keep the symmetry of
the DARK / LIGHT order, when inserting the LIGHT ends at the turning
point either add or delete a LIGHT. When changing from Ascending to
Descending, use only one light end between the two darks. When
changing from Descending to Ascending, there will be three light ends
to accompany the two DARK ends. Always keep the DARK / LIGHT order
and be consistent when making adjustments at the turning points.
Here
is the complete “As Drawn In” draft showing DARK & LIGHT
ends:
It
is difficult to see the threading and treadling pattern with this
type of computer draft. I usually write or print out the original
draft with the extra ends at the turning points to get the threading
for the DARK ends, leaving a space between each end. Then I write in
the LIGHT ends with a pencil or different colour:
With
this method, the pattern of both the DARK and the LIGHT ends is
clearly visible and logical.
To
weave, use the standard tie up. The above draft starts with DARK on
shaft 1 = DARK pick lifting shafts 1&2. Next, LIGHT on shaft 3 =
LIGHT pick lifting shafts 3&4, etc.
Alternate
two shuttles, DARK and LIGHT throughout and treadle as drawn in to
get the “M & W” pattern. If the pattern is written out and
DARK and LIGHT ends marked clearly it is easy to weave with above tie
up as feet will alternate from left to right.
Any
twill treadling draft without skips can be used with good results.
Follow same procedure as with the threading, first writing out the
treadling pattern adding extra ends at the turning points, leaving a
space between each dark pick, drawing in ascending or descending
arrows and then filling in the LIGHT ends according to the chart.
Nancey
Orosz was the weaver of this sample.
One of our members created a double weave runner with Huck Lace borders and Huck Spot Background for the 2015 weaving exchange. The red and white runner was created to enable her to create a woven item for her double weave study group and to create an item for the lace exchange. 
After submitting the runner for the exchange she wove 4 matching place-mats.
