I learned my lesson early on to ALWAYS make a swatch.
With a perfect Stockinette st swatch gauge, I started a child’s sweater. After 20 rows, I checked the gauge again and instead of 15 sts to 4", I now had 16 sts to 4".
Is this a common situation? And what do I have to do to get back to the correct gauge? It’s all Stockinette st working with the same needles I used to make the swatch.
Thanks for the help!
