When I am knitting cables, I always give a little tug down on them
after doing a crossing and it seems to help kinda stretch the stitches
a bit smoother since they do get all bunched up and weird looking
when you first do the cross. Because of all the manipulation
involved I think cables always look a bit weird right when you do
them but if you look at the ones further down the knitting that have
"settled" I think you'll find they look much better.
