I've made quite a few shawls over the past few years.
I created a pattern of three equilateral triangles, and made it in several sizes and colors. This is the largest, lying on the back of the sofa...
Recently I wore one to a gathering of former co-workers. Noting that my shawl kept falling off my shoulder, one of the women - a knitter herself - suggested I add buttons in the front and sides to make "sleeves."
I decided to give it a try - and I do like the result! It feels more like a jacket than a shawl... now that I have added the buttons.
