When you make a swatch, do you bind it off, break it from the rest of the yarn and then measure? Or can I just make the swatch, pull it off the needle and measure, and then frog it so I can reuse the yarn?
ETA: I just finished my swatch. It’s still unwashed & unblocked, but it’s measuring 4 x 4.5 and it’s supposed to be 4x4. How will that effect (affect?) my tank top?
