This 4 piece set (pullover, hat, booties & blanket) is worked with sport weight yarn at 6 stitches per inch. For a softer feel, the blanket is worked with the same yarn using larger needles, so the gauge is 5 sts = 1". You can see from the photograph that you can use solid or variegated yarn. A set could also include mixing solid & variegated.
