My knitting and vintage loving buddies will understand:
I got into a minor bidding war over this, ended up paying about twice what I meant to, but I'm so pleased to have it I'm not complaining (and I still got a bargain, I'm just cheap). It's an M.P. Handy Guide for Knitting and Crochet.
Look, it's even on Wikipedia (why is that not spelt Wikipaedia?):
(scroll down to "Complex Row Counters").
Yes, the sliders do stick a bit, but only a bit, I'm finding it insanely useful. Although I probably shouldn't be using it being a museum piece and all ;-)
Keen eyed obsessive knitters might also spot my new knitting technology. Oh yes, Addi Clicks! Handy! Although they the joins do catch a bit when knitting with the smaller size needles. Good thing I also have my Knit Picks. Can't have too many needles, specially when you're a little knitting ADD and have to start a new project every other day...
