I did a lot of changes when doing baby clothes. Especially because I just don't like garderstitch. And a LOT of baby patterns have garder... maybe because a lot of new knitters want to knit for babies? Or because it is stretchy?
But when you start with a change here, then you make one there, then this and then that... I only start hating it when the gauge does not come out and I have to start over a few times.
