Even though one slipped stitch managed to make a gaping hole in the second slipper, I had to hack and snip and yank and pull and waste all the yarn to get the mess undone to redo. The manufacture calls this fuzzy stuff that I twist with bulky yarn “Fun Fur”. It is a misnomer — not “fun” at all. When I’m testing yarns, especially “specialty” yarns, the first thing I do is make a simple good sized swatch and then attempt to undo it. I’ll be more attentive this next redo.
