ya know i used to as well and i think i discovered why when i was making my baby sock
(have you seen the picture, it is quite adorable!
i just realized explaining this could be hard...lol. When i am working with circ A i always keep the needle shaft of circ B in the loops of the stitches. i liked the fact that it gave me a little firmer surface to start the row on. after a few stitches i would pull it so that the loops on B were down on the cord instead because it was easier to work with then.
well for some reason when i was making the baby sock
i pulled circ B so that the loops were down on the cord right away and i was able to pull the work tighter....no ladders!
(and a really cute baby sock
(yeah i know i am not the first person ever to make a baby sock
but loooook how cute it is!
