I had draped this poor shawl over a thick plastic hanger and then added a few more shawls over it. The weight just caused some threads to break.
The final step was on the wrong side, which I did not picture. That involved catching the raw edges to the patch edges to prevent any further unraveling.
If you are curious to see the shawl before the damage and first aid, here's a link to my Ravelry project page.
