Elspeth (Rowan 37) turned into a mess of uncoordinated disaster. Lace holes in wrong places and dropped stitches, urgh, just a mess. I frogged the whole back and half the front and have started again. Now that I know the pattern repeat quite confidently, I'm hoping it will be a smooth knit.
I've got to say that the Knit Picks Shine is wonderful to work with. Its soft and cosy to touch and its managed to stay in tact post-frogging with no fuzzy bits. As to its durability after wash and wear, that I have yet to see.
