Over the last few months I've been trying to tighten up my knitting a little bit. Nothing drastic, but a bit of slow change so that it will become a habit. (I'm tired of having to go down 2 needle sizes to get gauge, and I want to write more patterns for other people to knit without making myself crazy trying to figure out what size needle normal people would need.)
The down side is that I've discovered I have a bad habit of bracing the left needle point against my right index finger in order to push stitches up into working position. Now that they're tighter, I have to push harder. And the circ I'm using for my cabled coat is really really pointy.
I've poked a hole in my finger.
