The challenge in designing this garment was making sure that it is durable enough to last through many years of wear and many trips through the wash. In wearing it, the weight of this heavy cloth is all concentrated on the shoulders. To help distribute that weight, I added wide flat-felled bands to the sides of the neckline. The inside is smooth and comfortable on the shoulders.
Then, at the points of the neckline, I attached a thick piece to the front and back. This stabilizes the spot that gets the most stress, preventing is from stretching or tearing.
But, the wearer doesn't have to worry about any of that stuff. Just throw it on, pack it in a suitcase, toss it in the wash, and enjoy!
