I'm working up a baby blanket sample using the Hayfield Baby Blossom Chunky introduced last week. Isn't it fun to see how the patterning looks knit up vs. in the skein?
Self-patterning yarns seem mysterious, but they use a yarn's intended gauge to deliver the effect. If you know how many stitches per inch the yarn will be knit at, you can determine the length of yarn that will be used to make that stitch, and color can be applied to the yarn accordingly.
The additional variable of how many stitches wide a piece is will change the width of the stripes, and may affect how the pink and green bits stack up, but as you can see, even imperfectly aligned, they still give the definite impression of little flowers.
The pattern I am using is the free Malt blanket from Tin Can Knits' Simple Collection. Since Baby Blossom Chunky knits to a slightly larger gauge, I've modified the numbers just slightly. A fun and quick knit!
