And when I say that, its true!!
The cuffs (and about 2 inches above them) have been successfully picked out and the new, tighter cuffs put in.
Aside from that awful "Oh no, I'm CUTTING my knitting" moment, it all went well, the DH is delighted and now I can get back to the 7 other projects I have on the needles!
Oh yeah, and I learned something new -- on the whole a very satisfying experience.
