I am thinking about doing the February Lady sweater in DK instead of the worsted it calls for. Anyone have any helpful experience in what changes Ill need to make?
It would make a big difference in size. You could check the gauge of your dk vs. worsted and multiply your stitches by the percentage difference.
If you're a small, it might be possible to make a larger size, but again, gauge, gauge, gauge.
Most people, including the designer, have said that you should err on the side of smaller not larger in this pattern so knitting it in your size may be fine. Since it's a raglan you could knit a bit longer if necessary, too. Do a gauge swatch and see how close you are.
I'm knitting the Lady Sweater in "sport DK" right now.
I checked my gauge, figured out that I'm getting 75% of the noted gauge and now I'm knitting according to the 44" size which is yielding approximately a 32-33" size sweater. It's working out nicely.
