Is there a rule of thumb for knowing how much sizing up or down your needles will change your gauge?
I often like to use yarns other than those specified for a given pattern. It is easy when the sts/inch are similar. However, often the sts/inch is different AND the needle size is different.
W/o making a swatch, is there a rule of thumb for “yeah, that’s in the ballpark” or “nah, I’d better keep looking”.
(Specifically, I am wondering if I could make the slanted v neck pullover from the Spring IK on the other link in Debbie Bliss Alpaca Silk DK. On the other hand, I had better quit buying yarn anyway, so it isn’t the end of the world if I can’t figure it out. More important is whether or not there is a rule of thumb for this sort of thing).
