Blanket Terminology.
Here are some terms frequently used to describe the construction and features of striped trade blankets:
Body: The largest area or background having the same appearance, usually a solid color. Also called the field.
Bars: The horizontal stripes or decoration at each end of the blanket. Bars typically vary in color and width among different park blankets.
Double fold: A standard width blanket having twice the length of a similar single size blanket due to it not having been separated (cut or torn apart) where the single blankets join together in the roll of blanketing coming off the loom. When folded, a double fold blanket acts like two joined single blankets one atop the other. Pendleton ceased manufacturing double fold blankets before 1940.
Felt bound: Trim sewn on the blanket edges made of thick felt. National park blankets typically had trim only on the blanket ends and not on the sides, which had selvage.
Field: Same as Body.
Overstitch bound: A machine sewn tight stitch, often overlapping, used for binding the edge of a blanket.Points: Short thick lines of thread, usually about 3 inches long on Pendletons, sewn into the edge of the blanket to indicate its size and weight. National park blankets came in four point or five point sizes.
Selvage: A plain weave in three or four rows along the sides of a blanket that provides a strong edge which is heavier and better wearing than the fancy weave of the blanket body.
