I don't know about that, but here's a story about the dangers of not listening to the voices in your head. You know, where you decide to make a lovely pair of soft red socks for CanAssist using yummy red Debbie Bliss Baby Cashmerino, and you have a pattern which will be quick and easy and uses that very yarn, which you have in your stash. And the pattern says to use 2.75mm sticks, which for me, using a sportweight yarn, was something I knew to be dangerous. Here's how it went:
Voice In My Head: Go up a stick size (at least) - they'll be too tight
Me: Nah, it'll be ok, they don't have to fit me, so it won't matter if they're a bit smaller
VIMH: Yeah, but you want them to actually fit someone, don't you?Me: They'll fit! And besides, I'm using my 3mm sticks for something else, and I don't want to use 3.25mm sticks or otherwise they'll be too loose...
VIMH: Gah! Well, don't say I didn't tell you...
So of course I cast on and was merrily knitting away. Every so often I'd hear:
VIMH: I knew they'd be too tight. Look how they don't stretch very far. TOO TIGHT!
Me: Shut up. They'll be fine.
And I got to the toe. And I had a work colleague with very slim feet and ankles to try them on. She couldn't get them over her heel.
VIMH: Remember what I said...?
Me: SHUT UP! They'll stretch a bit when I block them.
And so I finished the toe...but didn't kitchener it...the Voice was wearing me down.
VIMH: HA! I TOLD YOU SO!
Me: (whimpering) shut up...
