Here are more photos of the black horse hair piece. One shows it just off the loom, before cutting off the heading sticks. Note that the heading was WOVEN when I cut off the previous piece. The sticks were attached to the apron rod to put the warp back on tension so I could weave this piece. Look up the tip on Two-stick Heading. It is also described in my first books and my book, Weaving for Beginners.
Here is the back; also interesting.
