I can, thankfully, work on mine at work after the paperwork stuff gets done (and my boss doesn't come in, for some reason, in the middle of the night) but since I've come back to the path I've been reading like crazy and my stitching, alas, has suffered.
I routinely knit at the computer. While in chat. I've even figured out how to knit while reading a hardcover or trade paperback. (regular paperbacks are too small without breaking the spine, don't like doing that).
Me? Obsessed? NEVER!
I used to do cross stitch, but I got annoyed too many times when I got the wrong thread. Then I had a kid - and knitting is just safer around a kid, IMO. at least I can SEE where I put the needle!
