This is the tale of my learning to weave on a four harness loom in less than a week at my LYS, The Fiber Factory and my very good teacher, Susan Clark. I must apologize first that I forgot to pull out my camera while I was warping my board. I took a picture anyway.
Here is the warping board with the guide string still attached. We followed the course of the string to warp on 3 yards of threads. It took many trips. We also learned to use crochet loops to hold groups of thread together and be able to count how many yards had already been wrapped.
I am now just waiting to wash this so it fulls and then I will cut off the loose ends and make a table runner with it. Finished measurements are 10.5" x 63".
