I just washed two scarves that I wove in bamboo yarn. I washed them and when I placed them on a towel to dry, I noticed that some of the tassels are loose and some have actually untwisted! I knotted the ends, so it is not the knot. I never had that happen before. I wove two other scarves and gave one away. I didn't check those tassels before I gave them away. I just thought the scarf looked ok, now I am wondering if I need to ask for the scarf back to check? Anyone have an idea why the tassels didn't stay twisted well? -Ruthie
