i finished them. i LOVE them. most comfortable handknit socks i ever made, and i mean under a shoe! and that's with, remember, NO TOE SHAPING because i screwed up. if they are this good with NO toe shaping, imagine how great the next pair will be!!
and this heel. this replacable heel. i love it. that is not to say that i'll never knit a gusseted heel again but gosh -- why do it? this is the BEST heel -- and if you are doing a pattern or colorwork on your socks, using a replacable heel means you don't have to think at ALL about how to expand your pattern to incorporate increases or anything.
and truly, that invisible toe cast-on is the best. i may use it for anything i knit in the round that is eventually meant to be "two-sided". i'm just so pleased with the whole endeavor.
