There are three times as many weavings with complete widths as with
complete lengths; 60 as compared to 20. Clues to the wrappings or
blankets of which these breadths were sections are frequently
furnished by traces of stitchery and broken threads on the side
selvages. As shown by table 2 and figure 3, the five narrowest
complete breadths (Group 1) are within a range of 4 to 12 inches.
Narrow widths can be woven most rapidly on the backstrap loom.
Complete breadths in Group 2 (18 specimens) fall within the range of
14 to 20 inches. These widths, also, can be woven without much effort.
Seaming together narrow breadths appears to have been preferred to
weaving wider ones equal to the two or three which compose some of the
rectangular specimens.
