Because Soren kept playing with the thread. Ripped off one double needle of stitches as I neared the end of a purl row. To all you other knitters out there - you know what I am talking about. And you might be shocked, that, in fact - it didn't bother me much. Because I am glad that he is interested in the thread, in the needles, in this crazy continuous knot forming into hand/arm mitts. I encourage him to drag the dog food holder into the bathroom, root through toothbrushes, pick a toothpaste and brush his teeth - even though I think he is playing more with the faucet than scrubbing. I love watching him grow and learn - and more than that, I appreciate that he wants me to be a part of it.
