I have the mulberry tree shawl as well as a LV shawl. I have not found either have bobbled.
I have found the LV shawl has pulled a lot easier than my Mulberry which I have also pulled a little. I find them as warm as each other.
When I went and looked at the Tamara verse the mulberry tree shaelbI felt the Tamara felt too thin.
I also have a couple of the mulberry lambswool scarfs which are really warm and again no issues with bobbles. These are surprising big as you want wear like a shawl around your shoulders.
