Count the number of rows per inch by turning your measuring tape 90o. Line up the tape along the left edge of a vertical column of stitches. I counted 5.5 rows between the 2 and 3 markers -- almost 6 rows. Measuring again in a different spot, I counted only 5 rows. A third sample counted 5 rows again, so my gauge for this swatch is 4 stitches and 5 rows per inch.
Wondering how to change your gauge? Maybe our Not Too Tight Tutorial can help!
