I sat down yesterday to see if I could snip out the seams on the weirdly twisted part of TSKP and on the very first snip managed to cut the wrong strand, making a nice hole in one of the pieces. The worst part was that it wasn't even the piece that seemed to be causing the twisting.
So I resigned myself to sitting down and dutifully frantically reknitting all four pieces and rethinking the assembly of this most confounding section. I started last night and finished this evening. Just got everything seamed up and ran it down to my car to hide it before David got home.
