The feedback from various sources overwhelmingly say “continue with the pattern.” And they are right. The shawl will be much too big for me to wear. Although, wearing the shawl was something that never crossed my mind. My goal was to make a shawl out of the yarn I spun, and to use as much of it as possible on a single item. The actual use of the item was never part of my thought process.
So thank you, everyone, for putting that question back into the equation.
I will finish the shawl as the pattern is written and make something out of the remainder. I should have enough to make a smallish stole. Perhaps a variant of another Eugen Beugler pattern, Lace Dream. I can do it lengthwise and see how deep I can make it before I run out of yarn.
