Tabby, also called plain
weave, is the most basic of weave structures and a great place to start for new
weavers. For my first weaving project, I
decided I use to use the small 24 inch rigid heddle loom I already had, and
work with tabby (partly because rigid heddles work best for tabby and partly because
I had almost no prior weaving experience).
The basic structure is very
simple. The weft threads travel over
every other warp thread, alternating each row to create the weave. This can be achieved with finger manipulation
or needle weaving, but the rigid heddle makes manipulating the warp threads
much quicker and simpler, allowing the weaving to raise or lower the threads
all in one motion. The primary
disadvantage to this style of loom (aside from having only one heddle or shaft)
is that the heddle is free-floating and doubles as the beater, making it
difficult to maintain an even beat and keep the selvedges straight.
The cloth was tabby woven
using a rigid heddle loom at 10 DPI at the full loom width of 24 inches. After
weaving, the cloth was fulled in a washing machine. Pre-fulling, the weave was
quite open and relatively even, though some areas were packed more tightly than
others (this was my first major weaving project and the first time I had worked
with a wool warp, so there was a bit of a learning curve in this process).
After fulling, the weave evened out a great deal and packed down considerably.
By the end of the fulling and dyeing process, the warp and weft were barely
visible and a compact, water repellent fabric had been produced, as can be seen
in the finished piece. This is significantly thicker and denser than the cloth
used in the extant Dublin caps, but will serve as a useful warm layer at cold
and wet events.
The cloth used to make my
Dublin-style Viking hood had been intended for another project, but due to
excess shrinkage in the fulling and dyeing process was not suitable for my
intended use (a later period hood). After making a pair of mittens out of part
of the length of fabric, I had a piece left which was just large enough to make
this cap if I placed the fold along the back of my head rather than across the
top (kismet!). As conservation of resources seems within the spirit of the time
period, this alteration of the basic pattern seems to be plausible if not
entirely supported by the archeology in Dublin and Jorvik.
Of the twelve caps and three
remnants of caps studied in Heckett, nine of the caps and two of remnants are
wool. All of the examples are tabby woven, with an even weave structure. All
but one are classified as having an open weave. The wool caps are woven at a
range of 12 to 23 warps per centimeter, with wefts ranging from 9 to 20 per
centimeter. The cloth for all of the caps is lightweight and quite fine, and
some of the silk is very delicate. At least some of the hoods seem to have been
purpose-woven on narrow warps. All of the wool caps analyzed in Heckett have
selvedges along two sides, while the silk caps all appear to have been cut to
size from wider pieces of cloth. Most have not been analyzed for dye, but of
those that have two were undyed, two showed traced of iron mordant.
