Ok I can feel you on this one.......
I just knit my first pair of gloves about a month ago and have knit everyone in my family a pair since. and a couple more for my self. I didnt want to use a preset pattern so I used this.....
I dont use patterns for my socks either...I like the custom fit method
1)DO A GAUGE SWATCH!!!!!!
2)measure your foot/hand
3)multiply the result of #2 x #3 = cast on stitches
At this point its a matter of how you want it to fit. you have cast on stitches that will fit your foot/hand comfortably but you may want to adjust that a bit for a looser/tighter fit.
I take %10 off of my CO stitches for my socks because i like a little hug when i walk.
I leave the cast on the same for my glove cuz...well....its just comfy that way.
That pdf was a huge help for me as far as gloves go but i knit socks and they say if you can knit socks then gloves is a no brainer. As it turns out.....they're right.
